The Turkish prime minister announced on Wednesday night that Turkey had fired artillery at targets in Syria, in retaliation for Syrian mortar fire that fell in a Turkish border town and killed five Turkish civilians. It was the first instance of significant fighting across the Turkish-Syrian border since the Syrian uprising began last year, and raised the prospect of greater involvement by the NATO alliance, to which Turkey belongs.
“This atrocious attack was immediately responded to adequately by our armed forces in the border region, in accordance with rules of engagement,” said a written statement from the office of the prime minister, carried by the semiofficial Anatolian News Agency. “Targets were shelled in locations identified by radar.”
“Turkey, in accordance with the rules of engagement and international law, will never leave such provocations by the Syrian regime against our national security unrequited,” the statement added.
NATO said it would convene an urgent meeting on the issue Wednesday.
