Al Jazeera's İdil Güngör, reporting from the Kilis refugee camp in Turkey, says clashes between Syrian government forces and opposition fighters could be heard across the border on Tuesday.
Some of the bullets even reached the camp, but Turkish authorities insisted the Syrian army had not targeted the camp, saying the bullets were stray bullets.
About 200 new refugees came to the camp on Tuesday. Seven of them were injured and are now being treated in hospitals.
The refugees are not allowed to leave the camp for shopping or other errands in nearby cities, except with government permission and on special buses.
