ANKARA (Reuters) - A Turkish court on Sunday (July 3) remanded 13 alleged Islamic State militants in custody pending trial in connection with suicide bombings at Istanbul's main airport last Tuesday that claimed 45 lives.

The 13 included three foreigners, Dogan, a private news agency said.

Three militants opened fire outside Ataturk airport's international arrivals terminal on Tuesday night before two of them entered the building and blew themselves up. A third militant detonated his explosives at the entrance.

"The terrorist organisation called Daesh, which burnt our hearts in this holy month, is the biggest form of evil that targets our religion," President Tayyip Erdogan told a ramadan dinner in Istanbul on Sunday. "They have no links whatsoever to Islam or Muslims," Erdogan said.

A total of 49 people are still being treated in hospitals from the attack and 17 remain in intensive care, Istanbul authorities said on Sunday. Two Russian nationals have been identified as suspected Islamic State suicide bombers in the attack, Turkish media said on Friday.
