In Turkey, one police officer has died after an attack on a bus in the north of the country, near to where Turkish Prime Minister Tayyip Erdogan had been holding an election rally.
The police vehicle was escorting a ruling AK party bus, but the premier had already left the city of Kastamonu by helicopter before the attack took place.
The unidentified attackers reportedly threw a grenade at the bus before opening fire. Two other police officers were wounded.
Campaigning has begun for a parliamentary election on June 12 that is expected to result in Erdogan winning a third consecutive term.
He blamed separatist militants for the attack, casting suspicion on the Kurdistan Workers Party (PKK) and its affiliates.
The PKK ended a six-month ceasefire in February and there have been fears of rising violence ahead of the election.
