Dubai's police chief said WikiLeaks will confirm his charge that Israel's Mossad secret service was behind the January 20 murder of a Hamas commander visiting the emirate, in a newspaper report on Friday.
"The leaked document will prove the truth about Mossad's involvement, but there are certain people that will still deny it even with the leaked documents," Dahi Khalfan told the English-language Gulf News.
WikiLeaks founder Julian Assange, quoted on the website of Al-Jazeera television, has vowed to release "sensitive" documents on the Israel-Hezbollah war of 2006 and on Mahmud al-Mabhuh's murder in his Dubai hotel room.
Khalfan, who came out in support of the WikiLeaks campaign of releasing US diplomatic cables, has said ever since the early days of Dubai police's probe into the killing that Israeli agents assassinated the Hamas commander.
Mabhuh, a founder of the military wing of the Palestinian Islamist movement Hamas, was found dead in his Al-Bustan Rotana room near Dubai airport. He was wanted in Israel for the alleged murder of two Israelis.
He had been drugged and asphyxiated, apparently by a group of people seen on hotel closed-circuit security cameras following him to his room.
Twelve British, six Irish, four French, three Australian and one German passports were used by the 26 people believed linked to the murder, according to Dubai police.
