Turkish military planes have scoured the Iraqi border for Kurdish rebel camps, after diplomatic talks in Ankara to avert a major cross-border operation into northern Iraq failed.

Turkey has massed up to 100,000 troops, backed by fighter jets, helicopter gunships, tanks, and mortars, on the frontier.
It has warned of a possible offensive against about 3,000 PKK rebels using Iraq as a base from which to carry out deadly attacks in Turkey.
Turkish Prime Minister Tayyip Erdogan has taken a swipe at western countries for not helping Turkey fight the PKK, criticising what he called an approach of "your terrorist is good, my terrorist is bad".
