The victims, who were eating at a restaurant when gunmen opened fire, were reportedly Turkey’s deputy consul in the city and an Iraqi civilian. Turkish President Recep Tayyip Erdogan condemned the “heinous attack”. No-one has so far said they were behind it. The Kurdistan Workers’ Party (PKK), which has fought Turkey for decades and has bases in Iraq, has denied any role.

“We have no knowledge about an incident of shooting and killing of Turkish consulate officials in Irbil”, a spokesman for the group’s military wing, the People’s Defence Forces (HPG), told the Iraqi Kurdish Dwarozh News website.
