The bill Thursday opens the way for unilateral action by Turkey's armed forces inside Syria without the involvement ofTurkey's Western or Arab allies. Turkey has used a similar provision to repeatedly attack suspected Kurdish rebel positions in northern Iraq.
Still, Atalay said Turkey's "main priority" was to "act together with the international community."
"That is why we called on NATO and the United Nations to take up the issue," Atalay said.
The NATO military alliance, of which Turkey is a member, met at an emergency session in Brussels and condemned the attack on Turkey. NATO demanded "the immediate cessation of such aggressive acts against an ally" and urged the Syrian regime to "put an end to flagrant violations of international law."
The Turkish response to the shelling was prompt — it fired salvos of artillery rounds deep inside Syria.
Mustafa Guclu, a witness in Akcakale, said the Turkish military fired five rounds of artillery "after midnight" toward Syria and another round around 5 a.m. on Thursday.
"I have not heard any more shelling since then," he told the Associated Press.
The Syrian mortar shell damaged the door and walls of a house in Akcakale, while shrapnel poked holes and shattered windows of neighboring houses and shops.
