Turkish PM Ahmet Davutoglu has promised to boost security along the country’s border with Syria, after 30 people were killed by a bomb in the town of Suruc, the BBC reports.
Investigators think the blast was caused by a female suicide bomber from the Islamic State group.
Correspondents say Turkey is cracking down on the militants, after previously being accused of ignoring them.
But the blast triggered violent protest in Istanbul, with police using water cannon, teargas and rubber bullets.
Monday’s bomb hit a group of youth activists planning to cross into Syria to help rebuild the town of Kobane.
