2016 Nagorno-Karabakh conflict
The 2016 Nagorno-Karabakh conflict, also known as the Four-Day War, April War, or April clashes, began along the former Nagorno-Karabakh line of contact on 1 April 2016 with the Artsakh Defence Army, backed by the Armenian Armed Forces, on one side and the Azerbaijani Armed Forces on the other.
The clashes occurred in a region that is disputed between the self-proclaimed Republic of Artsakh and the Republic of Azerbaijan. The region includes the former Soviet Nagorno-Karabakh Autonomous Oblast and the surrounding districts of Azerbaijan under the control of Armenian forces at the time. Azerbaijan claimed to have started a military operation to prevent purported continuous Armenian shelling of civilian areas in Azerbaijan. However, there was no evidence of Armenian shelling. Until the 2020 Nagorno-Karabakh war, the clashes were the worst since the 1994 ceasefire agreement signed by Artsakh, Azerbaijan and Armenia.
A ceasefire was reached on 5 April between Azerbaijan and Armenia in Moscow. The Nagorno-Karabakh authorities also welcomed the oral agreement. After the agreement, both sides accused each other of violations. Azerbaijan claimed to have regained of land, while Armenian officials suggested a loss of of land of no strategic importance. However, the International Crisis Group reported that those heights were of strategic importance.
Officially, Baku reported the loss of 31 servicemen without publishing their names. Armenian sources claimed much higher numbers varying between 300 and 500. The Ministry of Defence of Armenia reported the names of 92 military and civilian casualties, in total. The US State Department estimated that a total of 350 people, both military and civilian, had died. Official sources of the warring parties put those estimates either much higher or much lower, depending on the source.
Background
The First Nagorno-Karabakh War ended with a ceasefire agreement between the warring parties that came into effect on 12 May 1994. Violations of the ceasefire occurred periodically in the following years, with notable escalations in 2008 and 2010, but incidents especially increased since 2014. According to the International Crisis Group, there were 60 deaths total, both military and civilian, in 2015 alone because of breaches of the ceasefire. The April 2016 clashes were the most serious breach of the 1994 ceasefire until 2020.Among the possible reasons behind the escalation of the conflict was the worsening economy of Azerbaijan. The collapse of oil prices in 2015–16 have been frequently cited, with clashes being used to distract the Azerbaijani population from rising prices and unemployment. Alternatively, some Armenian sources blame Turkey for provoking violence. Some Turkish commentators have suggested a Russian strategy to destabilize the region.
Azerbaijan has been openly preparing for offensive operations against Nagorno Karabakh for several years, as evidenced by the continuous massive military buildup, as well as the Azerbaijani authorities' numerous statements in favor of a military solution to the conflict. Thus, on 23 March 2015, Azerbaijan's Minister of Defence stated that the Azerbaijani military had accumulated the necessary weaponry to destroy 70 percent of opposing forces in a first strike. In February 2016, US Director of National Intelligence James Clapper warned that Azerbaijan's military buildup combined with deteriorating economic conditions was increasing the risk of an escalation in 2016.
On 19 March 2016, President Aliyev stated: "To resolve the conflict, in the first place it is necessary for our country and army to become even stronger. A lot is being done in this direction. Today, we have gained full advantage on the line of contact." Furthermore, in his speech, president Aliyev openly accused the Minsk Group Co-Chairs of provocation against Azerbaijan and had stated that Azerbaijan's confidence in their activities had been completely undermined.
Combat operations
The fighting was focused mainly on the front line with a length of 257 km. Each side blamed the other for the outbreak of clashes around the towns of Martakert, Tartar, Aghdam, Martuni, and Fuzuli. According to Armenian sources, on the night of 1 April and early morning of 2 April, the Azerbaijani side launched large-scale attacks along the contact line between Karabakh and Azerbaijan. On 2 April, a 12-year-old Armenian boy was killed as a result of missile artillery attack from a BM-21 Grad near the border with Martuni. Two other children were wounded as well. On 2 April, Azerbaijani positions and inhabited places near the front line came under fire from Armenian military, armed with mortars and high caliber grenade launchers, that killed 2 people and wounded 10 civilians. According to the Azerbaijani Ministry of Defence, during a rapid counter-offensive, the Armenian side's front defence line was broken in multiple places and several strategic heights and inhabited places were retaken. An AFP journalist confirmed that the Lalatapa heights were also under Azerbaijani control. The Azerbaijani side claimed that they had captured some areas, including heights near the village of Talysh, as well as the village of Seysulan. an unmanned aerial vehicle of Armenia was claimed to be shot down in Fuzuli as well. On 8 May the Armenia's First Channel release footage from military positions near Seysulan. 14,400 people living in villages were affected by clashes, but no internal displacement or immediate humanitarian need was reported.Armenian Ministry of Defence spokesman Artsrun Hovhannisyan sharply accused Azerbaijan of launching an unprovoked coordinated ground offensive against Armenia's forces, saying the Azerbaijani military used warplanes, tanks and artillery to try to make inroads into Nagorno-Karabakh. During the first day of fighting, Armenian forces claimed to have destroyed at least three Azerbaijani tanks, two military helicopters and two unmanned drones, photographs and videos of which surfaced on the internet. Armenian frontline positions were reinforced, heavy artillery was brought forward, and in the capital Stepanakert reservists were called up.
On 3 April, Armenian military authorities announced that Artsakh Defence Army forces had recaptured positions around Talysh, On 6 April, news footage shown on Armenia's First Channel revealed Armenian journalists and NKR troops freely mingling on the streets of Talysh and Madagiz. On 8 April, news footage shown on an Azerbaijani TV channel showed the Azerbaijan military installations purported to be near the Talysh heights. On 11 April, news footage from Armenia's First channel showed the Talysh heights under the control of Artsakh troops. Again on 8 May, news footage from Civilnet showed journalist Tatul Hakobyan with some NKR soldiers at Talysh heights near Naftalan. Later, Defence Minister Zakir Hasanov stated that if shelling of Azerbaijani settlements by Armenian forces did not cease, Azerbaijan would consider launching an artillery bombardment on Stepanakert. On the same day, the Azerbaijani Ministry of Defence announced a unilateral end to hostilities. The Azerbaijani Ministry of Defence stated that should Armenian shelling pursue, Azerbaijan would continue its offensive.
On 4 April, the Azerbaijani Ministry of Defence reported that an Armenian command and control center had been destroyed and released a video which captured footage of the attack. On 5 April, a strategically important military base in Madaghis which is on the main road leading to Aghdara city and a bus carrying "Yerkrapah" Armenian volunteers were fired. The Azerbaijani Ministry of Defence claimed that along with numerous military personnel, two high-ranking Armenian officers were killed as a result. The same day, the Armenian defence ministry announced that an Azerbaijani drone, identified as an Israeli-made IAI Harop, attacked a bus carrying Armenian volunteers enlisting in military service to the Nagorno-Karabakh town of Martakert by slamming itself against it, killing seven people aboard including the heads of two rural communities within the NKR. It is believed to be the first ever combat use of the drone anywhere. An Israeli-made ThunderB surveillance drone was shot down on 2 April according to the Artsakh defence force. Armenian officials later protested Israel's supply of weaponry to Azerbaijan. Some Azerbaijani sources claimed that Madagiz was under Azerbaijani control, citing Azerbaijan Ministry of Defence but Armenian side reported this to be false. Later, the Armenian side published a video to prove that Madagiz remained in their control.
On 5 April, the Azerbaijani Ministry of Defence claimed that the mutual ceasefire agreement, which was agreed upon in Moscow by the heads of Azerbaijan's and Armenia's militaries, was breached by Armenian forces which shelled Azerbaijani positions near Tap Qaraqoyunlu with 60, 82 and 120 mm mortars.

According to Azerbaijani claims, Armenian Armed Forces directed high caliber artillery fire at a mosque, schools and residential buildings as well as civilian infrastructure. Damage to houses in Azerbaijan by Armenian artillery fire was reported in the Russian press.
According to Azerbaijan, on 7 April, Armenian armed forces shelled an ambulance evacuating injured Azerbaijani civilians in the Aghdara-Goranboy area. Also, according to the Azerbaijani Ministry of Defence, on 7 April, an Armenian "X-55" style drone was shot down by Azerbaijani forces while trying to fly over the frontline.
The Ministry of Defence of the Artsakh Republic published some aerial photos to prove that Azerbaijan deploys military units near populated areas and violated the Article 52 of Geneva Convention. During a BBC visit to Azerbaijan's side of frontline, a team of BBC journalists asked to see and ensure where the alleged military objects are placed but the Azerbaijani Ministry of Defence refused for "safety reasons".
On 8 April, artillery fire was exchanged between Armenian and Azerbaijani forces, with the Armenians reporting two soldiers killed. A temporary ceasefire agreement mediated by the International Committee of the Red Cross and field assistants of the OSCE, allowed for both sides to collect dead and missing soldiers. On 14 April, the Azerbaijani government reported that one of its soldiers had been killed by Armenian forces on the line of contact. On 15 April, Nagorno-Karabakh reported one of its soldiers had been killed in action with Azerbaijani forces.
