New Israeli strikes against Gaza occurred late on Monday night in the east of Gaza City, wounding 17 people.
Witnesses said the target of the raid was a car repair workshop, AFP reported.
Earlier on Monday, Israeli Deputy Foreign Minister Danny Ayalon issued a death threat against Hamas leaders.
Israel regularly carries out attacks on Gaza, killing and injuring Palestinians. Tel Aviv launched a deadly war on the strip at the turn of 2009.
More than 1,400 Palestinians were killed during the three-week Israeli land, sea and air offensive in the impoverished coastal enclave. The offensive also inflicted $1.6 billion damage to the Gazan economy.
Some 1.5 million people in the Gaza Strip are being denied their basic rights, including freedom of movement, and their rights to appropriate living conditions, work, health and education.
Poverty and unemployment rates stand at approximately 80 percent and 60 percent in the Gaza Strip respectively, reports say.
