ISRAEL and the Palestinians were locked in a deadly cycle yesterday, with militant groups vowing revenge for a raid that killed 14 on Sunday and the army promising no let up in its operations.

PALESTINIANS vowed to strike at the heart of Israel yesterday as some 10,000 mourners gathered at the funerals in central Gaza for the victims of a massive Israeli army operation.

THE militant group Hamas threatened revenge yesterday after Israel killed four of its members in a missile strike and declared anyone in the group a target for “liquidation.”

The Palestinian terror group Hamas vowed to have its revenge today after Israel killed four of its members in another missile strike.

Israeli helicopters killed four Palestinian fighters, including a fugitive Hamas commander, in a missile strike in the Gaza Strip, hours after its army chief declared all Hamas members "potential targets for liquidation".
