The armed group says Hussam Abu Harbeed, one of its leaders in Gaza, was killed in Israeli airstrikes.
An Israeli air strike in Gaza has killed Hussam Abu Harbeed, an Islamic Jihad leader, the armed group said.
The killings, on Monday, are likely to get a harsh response from the group fighting on the side of Hamas, the movement that controls the Gaza Strip.
The Israeli military said in a statement that Harbeed was “behind a number of anti-tank missile terror attacks against Israeli civilians”.
Shortly after Harbeed’s assassination, Islamic Jihad said it fired rockets at the Israeli coastal town of Ashdod.
At least three Palestinians were also killed in an Israeli air strike on a car in Gaza City on Monday, according to medics, after a night of heavy Israeli air strikes.
The Israeli military says Gaza fighters fired nearly 60 rockets into Israeli towns in one night, up from 120 and 200 in the previous two nights.
Hamas said its attacks were in retaliation for “ongoing attacks on Israeli civilians” and called the civilian victims “premeditated killings”.
At least 200 Palestinians, including 58 children, have been killed in the Gaza Strip since the latest violence began a week ago.
More than 1,300 Palestinians were also injured.
