A suicide gun and bomb attack on Istanbul’s Ataturk international airport, one of Europe’s busiest, has killed 32 people and injured 60 more.
Three attackers were involved, with one reportedly opening fire with a Kalashnikov as they targeted an entry point to the terminal.
Recent bombings in Turkey have been linked to either Kurdish separatists or the so-called Islamic State group.

Charles Michel, the Prime Minister of Belgium whose capital city was targeted by bombers in March, tweeted from the EU summit in Brussels: “Our thoughts are with the victims of the attacks at Istanbul’s airport. We condemn these atrocious acts of violence.”
