Four members of Palestinian militant groups have been killed in Israeli military operations in the northern Gaza Strip.
Mourners buried one of the Hamas militants in Beit Lahiya
Two members of the Islamic Jihad group were killed by an Israeli attack air strike near the town of Beit Hanoun.
The men had been firing rockets at Israel, Islamic Jihad and the Israeli military said.
Earlier, Israeli soldiers shot and killed two Hamas militants near the town of Beit Lahiya.
Through the day, three rockets were fired from Gaza into Israel, one of which injured a woman at a college in the town of Sderot. Israel responded with air strikes.
"We targeted two men firing rockets at Israel. We apparently hit them," an Israeli army spokesman said.
Israel launched a second air strike after dark, shooting a missile at a vehicle in Gaza City but missing its occupants, witnesses said.
Israeli soldiers shot and killed two gunmen of the Hamas Islamist group earlier on Sunday as they approached a border fence with Israel.
Palestinian medics said the two men were killed near the electric fence surrounding the Gaza Strip, near the town of Beit Lahiya.
The Israeli army confirmed the clash. A spokesman said the men were armed with guns and grenades.
The Ezzedine al-Qassam Brigades, the armed wing of the Islamic group Hamas, said that "two of our fighters were killed in an exchange of fire" with Israeli troops, the AFP news agency reported.
Hamas took control of Gaza last month, after routing forces from the rival Fatah faction.
