Police in Dubai called for an international manhunt Tuesday to capture the killers of a Hamas terrorist leader last month.

Authorities are looking for an international hit squad of 11 people with European passports shown in a security video from hotels in Dubai.

The team of mercenaries allegedly used disguises to track and kill Mahmoud al-Mabhouh, a founder of the Hamas military wing, in his hotel room.

Meanwhile, Fayek al-Mabhouh, the brother of the slain Hamas commander, has blamed Israel's intelligence service, the Mossad, for the attack.

"It was Mossad which carried out or plotted this operation, but not on its own; rather with the cooperation of other agencies or agents, agents from Arab countries or from the West," Fayek said.

"It is possible that further surprising information will be disclosed in the future," he said. "We cannot rule anything out. But our accusation, in the first place, is leveled at the Israeli Mossad."

Sources in Britain also suspect the Mossad. So far, Israel has not responded to the accusations.
