Istanbul Besiktas Turkey: Stadium blasts kill 38 people
A twin bomb attack on police officers outside a football stadium in Turkey's largest city, Istanbul, has killed 38 people and injured many more.
A car bomb hit a police vehicle and a suicide bomber detonated a suicide vest in quick succession late on Saturday.
The blasts occurred near the stadium of top-division team Besiktas, two hours after a match. Ten arrests were made.
The government says initial findings point towards Kurdish militants, who have targeted police in the past.
Deputy Prime Minister Numan Kurtulmus told CNN Turk news channel that "arrows point" to the Kurdistan Worker's Party (PKK).
Thirty of those killed in the attack were police officers, officials say.
A further 155 people were being treated in hospital, 14 of them in intensive care, health officials say.
No group has said it was behind the attack but a wave of bombings in Turkey this year has been carried out both by the PKK and so-called Islamic State (IS), says the BBC's Mark Lowen in Istanbul.
President Recep Tayyip Erdogan said the explosions "aimed to maximise casualties".
But they came two hours after the end of the match between top teams Bursaspor at Besiktas at the Vodafone Arena.
Local media reported that fans had already dispersed. Bursaspor posted on Twitter that it knew of no injuries to its supporters.
