Dubai warned Israeli intelligence as well as Hamas of working "behind its back" on Wednesday, in the wake of the assassination of Hamas strongman Mahmoud al-Mabhouh last month.

Dubai police chief Dahi Halfan warned international intelligence agencies from working "behind our back," saying anyone who did so "should be wary of his own back.

Halfan added that that threat was also applicable "to any intelligence organization around the world, whether Mossad, Hamas or any other agency."

The Dubai police chief added that he believed the Hamas leader was in Dubai for business and not for any kind of arms transactions.

Al-Mabhouh, who was reportedly responsible for the smuggling of Iranian arms to Gaza, was found dead in his hotel room on January 20, the organization was quick to point the finger at Israeli intelligence, vowing revenge attacks.

Halfan added that if Al-Mabhouh would have been interested in meeting Iranian officials in Dubai, as the Israeli media has claimed, he could have done so in either Syria or Iran itself.

The Dubai police commissioner refused to reveal the identity of the suspects linked to the incident, denying a Hamas claim that the assassins had entered the country by participating in Minister Uzi Landau's entourage, when he visited Dubai earlier that month.

"Why would possible perpetrators choose to take part in a tightly watched delegation, only to exit Dubai using European passports," Halfan said.
