Turkish fighter jets began air strikes in two separate regions in northern Iraq against PKK, senior security sources said on Friday, reported Worldbulletin.
"Last night two separate regions were bombed where the PKK was believed to be taking shelter," a high-ranking security official told Reuters.
The mayor of the town of Jarawa in Iraq, Azad Wassu, said there were Turkish air strikes on the Kandil mountains from 10 p.m. on Thursday until 12:30 a.m. He said there was no damage or casualties.
Turkish armed forces have conducted several cross-border operations, including a brief land offensive, against the PKK bases in mountainous northern Iraq over the past 12 months.
Turkey says it believes that thousands of PKK militants use northern Iraq to stage attacks inside Turkey.
The government has asked parliament to extend a mandate, which expires next month, to launch further military operations against the PKK in Iraq.
Since a land offensive in February, Turkey's military has confined its cross-border operations to air strikes and shelling against PKK targets.
