Turkish troops have returned fire after a mortar shell from Syria again landed on their territory, Turkey's state-run news agency has reported. The Anadolu Agency quoted the governor of Hatay province as saying that Turkish troops "responded with fire" after the mortar round landed in a rural area of the province which borders Syria. No-one was reported hurt. Turkish artillery has fired at Syrian targets for two straight days after shelling from Syria killed five civilians in Turkey. On Thursday, Turkey's parliament also voted to allow cross-border military operations in Syria. The uprising against Syrian President Bashar Assad erupted in March 2011 and has gradually evolved into a bloody civil war, killing more than 30,000 people, according to activists. |
