Jerusalem ( CNN ) -- The patter of rockets from Gaza into Israel continued Wednesday , according to Israeli authorities . And an al-Qaeda linked group claimed responsibility for launches that occurred a day earlier . The steady drip of projectiles has irked the Jewish state , which Tuesday conducted its first airstrikes into the Palestinian territory since the cease-fire that ended eight days of raging hostilities in November . Two explosions outside of an Israeli city near Gaza led police bomb disposal experts on a search for new rockets Wednesday , said spokesman Micky Rosenfeld . `` We found one rocket that landed in the entrance of Sderot without causing injury , no damage . Luckily it fell in an open area . '' Explosives engineers are still looking for a second one , he said . `` It is the second wave of rockets in the last 24 hours . One rocket was fired yesterday and landed in the Eshkol Region . '' Israel Defense Forces said war planes accurately struck two terror targets in Gaza on Tuesday , but Palestinian security officials said the strike hit empty land , causing no injuries . The majority of rockets launched from Gaza lack precision and nose-dive into open areas in Israel . Defense minister Moshe Ya'alon lashed out at Hamas , blaming the Islamist party that governs Gaza for the rocket fire and justifying Israel 's military action . `` We will not let any fire drip down on our civilians or forces , '' he said . Obama : 'Peace is possible ' Small groups claim responsibility . Hamas has denied any connection to recent rocket strikes . The al-Qaeda affiliated Mojahideen Shura claimed responsibility for firing two rockets at the Eshkol region Tuesday , saying it was retaliation for the death of a prominent Palestinian prisoner who died the same day in Israeli custody . Retired Palestinian general Maysara Abu Hamdiya died of cancer at age 64 after being transferred from prison to an Israeli hospital . He had been incarcerated since 2002 in connection with the bombing of a Jerusalem cafe . His death triggered outrage among Palestinians , who accuse Israel of denying him treatment . 4,500 fellow inmates have gone on a three day hunger strike to protest his passing , according to a Palestinian prisoners ' association . Ya'alon stressed that there was no relation between Israel 's actions in Gaza and Abu Hamdiya 's death . Hamas has said a group called Khalid Ibn Al-waleed claimed responsibility for other recent launches at Israel , and that it has no connection to Hamas .

Ya'alon also vented anger at the Syrian government in Damascus , holding it responsible for an alleged attack in the Israeli held Golan Heights , an area Syria claims as its own . `` As far as we are concerned , the regime in Syria is responsible for everything that is happening in its territory and will not allow fire to fall on Israeli territory without reaction , '' he said . Ya'alon said the defense forces destroyed the source of the alleged attack overnight . READ RELATED : Israel conducts first airstrikes in Gaza since November , sources say .
