Violence has flared between Israel and Palestinian militants in Gaza, a day after seven militants and an Israeli soldier were killed during an undercover Israeli operation in Gaza.

Three others also wounded in the Israeli strike over the southern Gaza Strip, says health ministry.

Most of the Palestinians killed were carrying out knife, gun or car-ramming attacks, Israeli authorities say.

THE son of slain al Qaeda leader Osama bin Laden has threatened revenge against the United States for assassinating his father, according to an audio message posted online.

More than six months of violence leaves at least 209 Palestinians and 29 Israelis dead.
