Israel launched an air strike on the Palestinian Gaza Strip on Tuesday, the first such attack since an eight-day war in November, Hamas, the Islamist movement that controls the territory, and Israel's military said.
"Occupation planes bombarded an open area in northern Gaza, there were no wounded," a statement from the Hamas Interior Ministry said. An Israeli military spokeswoman confirmed there had been a strike in Gaza, but gave no further details.
Israel and Hamas agreed to an Egyptian-mediated truce in November, after eight days of fighting, in which 170 Palestinians and six Israelis were killed.
Israel launched the 2012 offensive with the declared aim of ending Palestinian rocket fire into its territory.
Earlier on Tuesday, the Israeli military said Palestinians launched three rockets at Israel. Two landed in Gaza and one hit an open area in southern Israel, causing no damage or injuries.
No Palestinian group claimed responsibility for the rockets.
