Israel's Defence Minister Moshe Yaalon warned on Wednesday that the state would respond to attacks on its people, AFP reported.
The warning came after Israel launched an air strike on the Gaza strip, in response to a rocket attack  on Tuesday night. Israel's military and Hamas confirmed the air strike.
“Occupation planes bombarded an open area in northern Gaza, there were no wounded,” a statement from the Hamas Interior Ministry said.
Israel also responded to fire in the occupied part of the Golan Heights , which borders Syria, returning fire across the armistice line towards the source.
"We shall not allow in any form the establishment of a routine of sporadic firing at our civilians or our forces," Yaalon  said Wednesday morning.
In the Golan Heights, our policy is that we have no intention of allowing a daily routine of firing from Syria towards Israeli territory, whether it is stray fire or not, and we will respond to that with a firm hand," he warned.
"The moment we identify the source of the fire, we will destroy it without any hesitation, as we did last night," he said.
"The Syrian regime is responsible for whatever happens on its territory, and we will not allow a situation in which fire leaks into Israeli territory without a response."
