Diyarbakir

: Around 20 people were wounded when a blast struck outside a police building early Friday in Turkey's southeastern city of Diyarbakir, the centre of the country's Kurdish community, security officials said.

Several ambulances were dispatched to the scene of the blast, which occurred just hours after police detained the two co-leaders of the country's main pro-Kurdish party and several other MPs in a major escalation of a broader crackdown against the minority group.
