A Palestinian related to a man suspected of being behind a knife operation against Zionists in the occupied territories was killed by undercover Zionist agents in hospital on Wednesday night, official Palestinian sources said.

"Abdallah Azzam Shalaldeh, aged 27, was killed by a unit of mustarabin (undercover agents) at the Al-Khalil hospital," said the Palestinian health ministry.

The occupation internal security services confirmed the raid, saying that Zionist forces fired when the man -- thought to be close to Shalaldeh Azzam, who carried out a knife attack in September -- tried to resist arrest.

Similar incidents have been recently repeated as the Zionist authorities getting mad by the courageous Palestinian youth who spare no chance to stab Zionist occupiers.
