A Turkish official says two attackers have blown themselves up at Istanbul's Ataturk airport after police fire at them.

Turkish media quoted Justice Minister Bekir Bozdag as saying 10 people were killed in the attack on Tuesday.

Turkey's state-run news agency quoted Bekir Bozdag as saying: "According to the information I was given, a terrorist at the international terminal entrance first opened fire with a Kalashnikov and then blew himself up. We have around 10 martyrs (dead) and around 20 wounded."

The official said the attackers detonated the explosives at the entrance of the international terminal before entering the x-ray security check.

Turkish airports have security checks at both at the entrance of terminal buildings and then later before entry to departure gates.

The official spoke on condition of anonymity in line with government protocol.
