1992 European Community Monitor Mission helicopter shootdown

The 1992 European Community Monitor Mission helicopter downing was an incident that occurred on 7 January 1992, during the Croatian War of Independence, in which a European Community Monitor Mission (ECMM) helicopter carrying five European Community (EC) observers was downed by a Yugoslav Air Force Mikoyan-Gurevich MiG-21, in the airspace above the village of Podrute, near Novi Marof, Croatia. An Italian and a French officer and three Italian non-commissioned officers were killed. Another ECMM helicopter flying in formation with the attacked helicopter made an emergency landing. The second helicopter carried a crew and a visiting diplomat, all of whom survived. The incident was condemned by the United Nations Security Council and the EC. As a result of the incident, the Yugoslav authorities suspended the head of the air force, and the Yugoslav defense minister, General Veljko Kadijević, resigned his post. The events followed the end of the first stage of the war in Croatia and closely preceded the country's international recognition.

The MiG-21 pilot, Lieutenant Emir Šišić, an ethnic Bosniak, disappeared after the incident. He was tried in absentia together with his superiors by Croatian authorities, convicted, and sentenced to extended imprisonment. Šišić was subsequently arrested in Hungary in 2001 and extradited to Italy, where he was tried, convicted and sentenced to 15 years in prison. In 2006, he was turned over to Serbia for the remainder of the sentence, but was released in 2008. Two other Yugoslav officers were tried in absentia in Italy and convicted in 2013, while Serbia was ordered to pay monetary damages to the victims' families. The victims were posthumously decorated by Italy and France.

Background

In 1990, following the electoral defeat of the government of the Socialist Republic of Croatia, ethnic tensions worsened. The Yugoslav People's Army (Jugoslovenska Narodna Armija – JNA) confiscated Croatia's Territorial Defence (Teritorijalna obrana - TO) weapons to minimize resistance. On 17 August, the tensions escalated into an open revolt by Croatian Serbs, centered on the predominantly Serb-populated areas of the Dalmatian hinterland around Knin, parts of the Lika, Kordun, Banovina and eastern Croatia.

Following the Pakrac clash between Serb insurgents and Croatian special police in March 1991, the conflict had escalated into the Croatian War of Independence. The JNA stepped in, increasingly supporting the Croatian Serb insurgents. In early April, the leaders of the Croatian Serb revolt declared their intention to integrate the area under their control, known as SAO Krajina, with Serbia. In May, the Croatian government responded by forming the Croatian National Guard (Zbor narodne garde - ZNG), but its development was hampered by a United Nations (UN) arms embargo introduced in September. The Brioni Agreement established an observer mission which was eventually called the European Community Monitor Mission (ECMM). The mission was tasked with monitoring the disengagement of belligerents in the Ten-Day War in neighbouring Slovenia, and the withdrawal of the JNA from Slovenia. However, on 16 August, an ECMM helicopter was hit by Croatian Serb gunfire in western Slavonia, injuring one of the pilots. This caused the ECMM's scope of work to be formally expanded to include Croatia on 1 September.

On 8 October, Croatia declared independence from Yugoslavia, and a month later the ZNG was renamed the Croatian Army (Hrvatska vojska - HV). The fiercest fighting of the war occurred around this time, when the 1991 Yugoslav campaign in Croatia culminated in the Siege of Dubrovnik, and the Battle of Vukovar. In November, Croatia, Serbia and the JNA agreed upon the Vance plan entailing a ceasefire, protection of civilians in specific areas designated as United Nations Protected Areas, and the presence of UN peacekeepers in Croatia. The ceasefire came into effect on 3 January 1992. In December 1991, the European Community (EC) announced its decision to grant formal diplomatic recognition to Croatia as of 15 January 1992.

Incident

On 7 January 1992, a pair of Italian Army Agusta-Bell AB-206L LongRanger helicopters operated by ECMM observers entered Croatian air space from Hungary. The helicopters were painted white and unarmed. They were flying from the Yugoslav capital of Belgrade to Zagreb via Kaposvár, Hungary. Authorities in Belgrade claim the helicopters were authorised to fly to Hungary, but that the pilots were warned they were not allowed to fly to Zagreb because no flights in Croatian airspace were permitted. The EC dismissed those claims, saying that the flight was approved in advance by Yugoslav air controllers. The approval was forwarded to the Yugoslav Air Force operations centre, but the order was never forwarded to the 5th Aviation Corps in Bihać, Bosnia and Herzegovina.

After the two helicopters were spotted by a Yugoslav Air Force tracking radar near Bihać, a pair of Mikoyan-Gurevich MiG-21s, which were on standby at the Željava Air Base near Bihać, were ordered to take off and intercept the aircraft. The MiG-21s, assigned to the 125th Squadron of the 117th Fighter Aviation Regiment, were piloted by Lieutenant Emir Šišić and Captain Danijel Borović. However, Borović declared that his aircraft had a problem with its engine, and Šišić took off alone. Šišić was guided to the incoming helicopters at an altitude of 3000 m, and then ordered to make a full circle with his jet. As he turned around, he spotted the helicopters flying below his plane, at an altitude of 600 m. Šišić requested further orders and was told to shoot the helicopters down. The order was issued by the duty officer at the Željava Air Base, Lieutenant Colonel Dobrivoje Opačić.

Šišić pursued the helicopters, firing shots in front of the helicopters, but his aircraft was not armed with tracer ammunition and the helicopter pilots were not able to observe that they were fired upon. Flying at a speed of 1000 kph, he switched to missiles and registered that the missile seekers had acquired the targets. Šišić fired two infrared homing R-60 missiles. One of the missiles flew between the two helicopters, while the other struck the engine of the lead helicopter. The helicopter was shot down near the village of Podrute, located in an area administered by the city of Novi Marof, north of Zagreb. The second helicopter had to crash-land to evade the attack.
