GAZA, April 5 (Xinhua) -- Israeli fighter jets carried out a series of air strikes on the Hamas-ruled coastal enclave in the Gaza Strip midnight on Saturday, with no injuries reported, medical sources and witnesses said.
Four successive air strikes hit a training post that belongs to militants in northern and southern Gaza Strip, Hamas security officials said, adding that explosions were clearly heard in the territory.
The air strikes were a response to the rocket fired earlier from the Gaza Strip into Israel.
Earlier on Saturday unknown militants fired a rocket from the Gaza Strip into southern Israel, causing no injuries or damage, local media reported.
It's the second round of strikes since Thursday when Israel carried out ten successive air strikes on military posts in the enclave in response to four previous rocket attacks.
Violence between Israel and Gaza militants has intensified recently as peace talks between Israel and the Palestinians stalled after the former refused to release 26 long-term Palestinian prisoners.
Last month Egypt mediated an extension of the 2012 ceasefire between Israel and Gaza militants. The original deal was brokered in November two years ago after the killing of three Islamic Jihad militants in southern Gaza Strip.
