Turkey: Three killed, nine injured in roadside bomb blast

At least three Turkish policemen were killed and nine wounded when a bomb exploded beside a passing police bus in Turkey's southeastern province of Diyarbakir on Monday. 

The explosion took place as the bus carrying riot police passed an area near Diyarbakir's Dicle University, a predominantly Kurdish region. 

"An attack was carried out when explosives... detonated as an armoured vehicle carrying our riot police was passing by," the governor's office said. 

There was no immediate claim of responsibility for the attack, but state-run Anadolu agency said the militant Kurdistan Workers Party (PKK) was behind the blast, AFP reported. 

The PKK has previously claimed responsibility for similar attacks.
