The Minister for Foreign Affairs, Micheál Martin, has said his Israeli counterpart, Avigdor Leiberman, told him he had no information about Israeli involvement in the killing of a Palestinian official in Dubai last month.
The two ministers held a 40-minute meeting in Brussels and discussed the use of forged EU passports, including five Irish ones, by the killers.
Following the meeting with Mr Leiberman, Mr Martin said the investigations by the member EU states concerned would continue.
European Union foreign ministers today condemned the use of forged European passports by the assassins.
European Union foreign ministers earlier condemned the use of forged European passports by the assassins.
Their statement made no direct reference to Israel.
Dubai police have blamed the Israeli spy agency, Mossad, for the killing of Hamas Commander Mahmud al-Mabhuh on 20 January. Israel has declined to confirm or deny any involvement.
Britain, Ireland, France and Germany last week called in Israeli envoys for talks at their foreign ministries after passports from these countries were implicated in the killing.
'We are extremely concerned that European passports... can be used in a different manner for a different purpose,’ Spanish Foreign Minister Miguel Angel Moratinos told reporters as he arrived for a meeting.
'We (the EU ministers) are going to discuss it and I hope we will issue a statement expressing our concern about this situation,' he added.
Israel's Deputy Foreign Minister Danny Ayalon said on Saturday that he foresaw no crisis in Israel's relations with Europe over the use of foreign passports in the murder as it had nothing to do with it.
Mr al-Mabhuh, a founder of Hamas' armed wing, was found dead in his hotel room in Dubai last month.
Dubai police released the names and photos of 11 suspects in the killing who entered the United Arab Emirates on European passports.
Those passports appear to have been falsified or stolen, as they belonged to what appear to be ordinary citizens shocked to learn of their being linked to the case.
