Tension has escalated along the Syrian-Turkey border, with gunfire from Syria injuring at least three people inside Turkey.

Two Syrian refugees and one Turkish translator were wounded in Monday's incident when the Kilis border refugee camp in Gaziantep province came under fire from the Syrian side of the border, a Turkish foreign ministry official said.

The incident occurred as reports indicated that Syrian government forces were trying to prevent refugees from entering Turkey.

Thousands of Syrians are sheltering in eight refugee camps set up in Turkey's southern provinces of Hatay and Gaziantep, while others have crossed into Lebanon, Jordan and Iraq.
