Smoke rises after an Israeli airstrike on Gaza City, November 21, 2012.
Israeli warplanes have carried out three airstrikes on Palestinian targets in the Gaza Strip, witnesses say.
Palestinian witnesses said that the Israeli aircraft bombarded areas in the southern town of Khan Younis and near the town of Rafah in southern Gaza during the early hours of Sunday.
There have been no reports of casualties.
The Israeli military confirmed the airstrikes.
In early April, Tel Aviv also conducted airstrikes on Gaza for the first time since a truce ended an eight-day Israeli war on the Palestinian territory in November 2012.
Over 160 Palestinians, including women and children, were killed and about 1,200 others were injured in the Israeli attacks from November 14 to 21.
Gaza has been blockaded by Israel since June 2007, a situation that has caused a decline in the standard of living, unprecedented levels of unemployment, and unrelenting poverty.
Israel denies about 1.7 million people in Gaza their basic rights, such as adequate healthcare and education.
