ISTANBUL — The Turkish military on Wednesday shelled targets in Syria after shelling from Syria hit a border village in Turkey, killing at least five people and wounding nine others.

The escalating tensions between the two neighbors prompted the North Atlantic Treaty Organization to convene an emergency meeting in Brussels late Wednesday at Turkey's request. NATO called on Syria to respect international law.

Late Wednesday, a mortar shell hit the Turkish town of Akcakale.

Ankara immediately blamed Syrian forces for the attack. A statement issued by the Turkish prime minister's office said Turkey's military had responded by shelling targets in Syria in response to what it called a "heinous attack." The statement said the response was within international law and rules of engagement.
