Turkish F-16 and F-4 warplanes have bombed Kurdish PKK rebel targets near the Iraqi border, as their ceasefire comes under increasing strain.

The air strikes on Daglica were in response to PKK shelling of a military outpost, the armed forces said.

Both sides have been observing a truce and it is the first major air raid on the PKK since March 2013.

Kurds are furious at Turkey's inaction as Islamic State (IS) militants attack the Syrian border town of Kobane.
