Turkish police detain 13 people over Istanbul airport attack
At least 42 people were killed in the triple suicide bombing at Istanbul's main airport.
ISTANBUL - Turkish police have detained 13 people, including three foreigners, in connection with the triple suicide bombing at Istanbul's main airport which killed 42 people, a Turkish official said on Thursday.
Police conducted simultaneous raids on 16 places in Istanbul, an official told Reuters.
At least 42 people died and more than 200 were injured when three men with guns and explosives attacked the airport on Tuesday night.
Officials have said the coordinated assault on Atatürk Airport bore the hallmarks of Isis, but there has been no official claim of responsibility.
A security source said at least one of the three suspected Islamic State suicide bombers may have been a foreigner.
"We're looking into the possibility of foreigners being involved. It is likely that at least one of them is a foreigner, but the investigation is still underway," the source said, declining to be named because details of the investigation have not yet been released.
'NOT ENOUGH' TO SHOW SOLIDARITY AFTER TERROR ATTACKS
Meanwhile, Turkish Foreign Minister Mevlut Cavusoglu said on Thursday that it is "not enough" to show solidarity in response to terrorist attacks.
Cavusoglu made the comments at a news conference in Brussels to announce the "opening" of Chapter 33 in Turkey's European Union accession process, which covers budget policy.
Cavusoglu also said that he expects European Union to meet its commitments regarding the visa liberalisation.
