The agents who assassinated top Hamas terrorist Mahmoud Al-Mabhouh in a Dubai hotel on January 20 apparently injected him with poison directly to the heart, causing an immediate heart attack, British newspaper London Times said. 

The Times reported Sunday that while forensic pathologists initially determined that the 50 year-old Hamas man had died of a heart attack, blood tests carried out in Paris found traces of poison in his blood system.

After killing Al-Mabhouh, the report said, the assassins took photographs all of the documents that had been in his possession and left his body in the hotel room, making sure to hang a “Do Not Disturb” sign on the doorknob. A short time later, the hotel staff found Al-Mabhouh dead.

Minister of National Infrastructures Uzi Landau denied categorically accusations by Hamas that Mabhouh's assassins had entered Abu Dhabi in his entourage when he visited the United Arab Emirates two weeks ago.

"My entourage went to an international conference in Abu Dhabi,” Landau said at the weekly cabinet session. “The wild Oriental imagination [of Hamas] ... stems from the anger over the fact that the Israeli flag is flying at Abu Dhabi.”

A Hamas official said on Saturday that Al-Mabhouh's assassins may have used false papers to enter Abu Dhabi, and speculated that they might have used Landau's visit to facilitate this.
