Turkey: 'IS' link to deadly Gaziantep blast
A suicide car bomber has killed two policemen in south-eastern Turkey.
The bomb went off outside police headquarters in the south-eastern city of Gaziantep, near the Syria border.
More than 20 people, some of them civilians, were injured in the early-morning explosion, which was heard several kilometres away.
Police later raided the home of a suspected member of the so-called Islamic State group, who is believed to have carried out the attack.
His father has been detained for DNA testing.
Turkey has been hit by a series of deadly blasts over the past year, linked either to Kurdish militants or IS.
