Palestinians carry a picture of Mahmoud Al Mabhouh as others carry his coffin during his funeral procession at the Palestinian refugee camp of Yarmouk, near Damascus, Syria.

DUBAI: Dubai’s police chief said that Israel’s spy agency, MOSSAD, could be behind the murder of a top Hamas leader at a Dubai hotel room.

“It could be MOSSAD, or another party,” police chief Dhahi Khalfan told AFP.

“Personally, I don’t exclude any possibility. I don’t exclude any party that has an interest in the assassination” of Hamas leader Mahmoud al-Mabhuh, Khalfan said.

“There were seven or more people holding passports from different European countries” in the group suspected of killing Mabhuh, Khalfan said.

He refused to name the countries, but added, “we are currently in contact with these European countries to verify the authenticity of the passports.”

The hardline Palestinian Hamas movement on Friday accused Israel of assassinating Mabhuh, who was found dead in his hotel room in Dubai on January 20, and vowed revenge.

Khalfan said that “it seems (Mabhuh) opened the door” of his room, letting his killers in.

“Mabhuh was suffocated,” Khalfan said, adding that “strangulation is possible.” On Sunday, The Times of London, cited unidentified Middle Eastern sources as saying that Mabhuh’s body was found by staff at the luxury Al Bustan Rotana hotel in Dubai.

The paper said that Mabhuh was travelling on a false passport and on arrival in Dubai was followed by two men described by local police as “Europeans carrying European passports.”

The hit squad injected Mabhuh with a drug that induced a heart attack, photographed all the documents in his briefcase and left a “do not disturb” sign on the door, the paper said.

It added that the Hamas leader was on a mission to buy arms from Iran to Gaza, and was tracked from the moment he boarded Emirates flight EK 912 from Damascus on January 18.
