At least four people have been killed in a bomb attack targeting a police vehicle in southern Turkey.
At the same time as the attack in the mainly Kurdish city of Diyarbakir, a simultaneous blast hit a police bus in the town of Kiziltepe about 70 miles further south. It is feared another two people were killed in the second attack.
A senior Turkish official said several people, including children, were injured in both attacks.
Officials have already blamed both attacks on the Kurdistan Workers' Party, or PKK.
