CEYLANPINAR, Turkey — Syria's air force bombed a rebel-held region near the border with Turkey for a second day Tuesday, killing at least one person and wounding three others, an official said.

The aerial attack raised the two-day death toll in the region to an estimated 31 people. Nearly 10,000 Syrians have fled into Turkey since Friday, seeking safety from shelling and bombing.

An Associated Press journalist saw air strikes around the Syrian town of Ras al-Ayn, just across the border from the southeastern Turkish town of Ceylanpinar. Plumes of smoke rose into the sky and Turkish ambulances rushed to the border to ferry wounded Syrians to Turkish hospitals.
