NATO airstrike has killed two people at a wedding ceremony in an Afghanistan's province, according to local media.

Axar.az reports citing Sputnik that, an airstrike conducted by NATO forces has killed two people and injured three others at a wedding ceremony in Afghanistan's eastern province of Ghazni, local media reported Monday.

The airstrike hit the province's Qarabagh district after the guests at the ceremony started firing shots into the air, celebrating the wedding, the TOLO news broadcaster reported, citing local authorities. The NATO forces reportedly mistook the gunfire for an attack against them and bombed the area in retaliatory fire.

Qarabagh’s district governor Abdul Sami Sharifi confirmed to the broadcaster that the bombing left two people dead and three others injured.

According to some other sources of the media outlet, the airstrike resulted in around 20 casualties.

Police reportedly launched an investigation into the incident.

Afghanistan has long been suffering from unstable political, social and security situation due to the simmering militant insurgency, including that of the Taliban and the Islamic State (Daesh) terrorist groups, both outlawed in Russia. The Afghan National Defense and Security Forces have been conducting joint operations to combat terrorism across the country.

The United States and its allies launched a military operation in Afghanistan in 2001 following 9/11 terror attacks. The mission in Afghanistan ended on December 28, 2014. On January 1, 2015, NATO announced its new mission in the country, called Resolute Support, to train and assist the Afghan security forces.
