Israel carried out airstrikes overnight against dozens of targets in the Gaza Strip, an official said Monday, with the military saying the raids were in response to rocket fire from the Palestinian enclave targeting a southern Israeli city.
"We have no intention to escalate," an unnamed Israeli official was quoted as saying by the Ynet news site.
"We do not currently know what the exact outcome of the strike is, but we shall clarify this," the official added.
The rocket that landed in Sderot, southern Israel, was fired on Sunday afternoon and caused no injuries.
Israeli analysts were quoted by local media as saying the extent of the retaliation was "exceptional" noting that it was far harsher than in the past for similar incidents.
Hamas, the Islamic group which runs Gaza, said the airstrikes were indeed an "escalation" and added that Israel would bear the responsibility for further slides towards violence.
