Diplomatic cables recently released by WikiLeaks indicate authorities in the United Arab Emirates debated whether to keep quiet about the high-profile killing of a Hamas operative in Dubai in January.

WikiLeaks founder Julian Assange has said his whistleblowing website plans to publish hundreds of "sensitive" US diplomatic cables on Israel, Al-Jazeera television reported on Thursday. "Sensitive and classified documents" on Israel's 2006 war on Lebanon and January's assassination in Dubai of Hamas militant Mahmud al-Mabhuh would be released, Assange told Al-Jazeera in an interview.

Egypt's foreign minister said on Saturday information released by the WikiLeaks website showed there was no contradiction between Egyptian officials' public and private statements, the state news agency reported.

WikiLeaks was battling to stay online on Saturday after Sweden issued a new arrest warrant for its elusive boss Julian Assange, while PayPal axed donations access for the whistleblowing website. The Times newspaper, citing police sources, reported that Assange - who is believed to be in Britain - could be arrested next week. Other media suggested that the 39-year-old Australian could face arrest within 10 days.
