Turkey's parliament has authorised troops to launch cross-border action against Syria, following Syria's deadly shelling of a Turkish town.
The bill, passed by 320 to 129, also permits strikes against Syrian targets.
But Deputy Prime Minister Besir Atalay insisted this was a deterrent and not a mandate for war.
Turkey has been firing at targets inside Syria since Wednesday's shelling of the town of Akcakale, which killed two women and three children.
The Turkish parliament passed the bill in a closed-doors emergency session.
