Turkish President Recep Tayyip Erdogan is presiding over a government security meeting in Istanbul to discuss Saturday night's deadly bombings near a soccer stadium.
Erdogan has vowed that those behind the twin bombings would be caught and face a heavy penalty. Prime Minister Binali Yildirim as well as several other cabinet ministers were at the security meeting.
At parliament, meanwhile, the ruling Justice and Development Party, the opposition Republican People's Party and the Nationalist Movement Party are reading a joint declaration condemning terrorism.
The car-and suicide-bombing near Istanbul's Besiktas stadium killed 38 people, mostly police, and wounded 155 people. No group has claimed responsibility but Turkish officials are pointing fingers at Kurdish rebels.
