Israel’s Foreign Minister Avigdor Lieberman has told his Irish counterpart that there was no evidence Mossad carried out the murder of a Hamas militant in Dubai.

Mr Lieberman met Irish Foreign Minister Michael Martin in Brussels to discuss the use of false Irish passports by the assassins, suspected to be Israeli intelligence agents. Six British passports were also used.

Mr Lieberman said: “The Middle East has a lot of internal struggles between nations and bodies that are not as democratic as Israel.” He clarified that he meant bodies such as Fatah and Hamas.

Mr Lieberman is due to meet British Foreign Secretary David Miliband in Brussels later.

The European Union has condemned the use of EU passports in the assassination of Mahmoud al-Mabhouh at a luxury Dubai hotel, but so far has not directly linked Israel to the killing.

The Foreign Minister of the EU member states issued a statement which said: "The EU strongly condemns the fact that those involved in this action used fraudulent EU member states' passports and credit cards acquired through the theft of EU citizens' identities."

"The EU welcomes the investigation by the Dubai authorities and calls on all countries to co-operate with it."

The Austrian Foreign Minister, Michael Spindelegger, said: "I see no context that it really was an assassination and that the Israeli government is involved. All those are assumptions, but there are no proofs."

Dubai’s police chief Dahi Khalfan Tamin has previously stated he is “99 per cent certain” that Mossad carried out the assassination and has called for an arrest warrant for Mossad chief Meir Dagan.
