Three Palestinians were killed, including a woman, and ten injured in an Israeli war jets' airstrike on a house in central Gaza Strip, medics and eyewitnesses said early on Saturday.

Ashraf al-Qedra, the health ministry spokesman in Gaza told reporters a 47-year-old woman and two other men were killed and ten injured in the airstrike on al-Zawayda town near the central Gaza Strip town of Deir el-Ballah, China's Xinhua news agency reported..

He also said that overnight, around 40 civilians, including men and women were injured in an Israeli war jets strike on another house in Sabra neighbourhood in Gaza city, three are in critical conditions.

The health ministry in Gaza said in a press statement that since the beginning of the Israeli large-scale air and ground offensive on the Gaza Strip in the first week of July, 2,096 Palestinians were killed and 10,540 injured.

While Israeli war jets have been striking on the Gaza Strip, militants fired more rockets into central and southern Israel. Israel Radio reported that a four-year-old boy was killed after a rocket hit his family house near Gaza Strip.

Meanwhile, Musa Abu Marzooq, the senior official in Hamas movement wrote on his personal page on Facebook that Hamas accepted to authorise Palestinian President Mahmoud Abbas to sign on Rome Charter.

Signing on Rome Charter would enable the Palestinians to join the international anti-crime court.

"Hamas signed before President Abbas on a paper that authorises him by the Palestinian factions, including Hamas to sign on Rome Charter that prepares for the state of Palestine to join the International Anti-Crime Court," he said.

Abbas had earlier this month conditioned that if the Palestinians want him to sign on Rome Charter, the Palestinian factions, including Hamas, should give him a written official authorisation.

The Palestinians representation in the United Nations was promoted in November 2012 to a non-member observer state, which enables the state of Palestine to join all international treaties and agencies, including the court in The Hague.
