Dubai's police chief says any traveler suspected of being Israeli will not be allowed to enter the United Arab Emirates, even if they carry an alternative passport.
Lieutenant General Dahi Khalfan announced the measure Monday at a news briefing on his investigation into the Israeli spy agency's alleged killing of a Hamas operative in Dubai.
Israel has neither confirmed nor denied its role in the January assassination of Mahmoud al-Mabhouh.
The 26 suspected killers used passports from Britain, Ireland, France, Germany and Australia.
The countries have protested to Israel about the use of forged passports, but have not directly accused Israel in the attack.
Police have arrested at least two Palestinians in Jordan in connection with the killing and have extradited them to Dubai.
In Geneva Monday, Iranian Foreign Minister Manouchehr Mottaki questioned the role the Western countries played in the assassination.
He told the U.N. Human Rights Council the nations should answer whether their security services, intelligence people or a part of their government were involved.
Israel says the Hamas commander killed in Dubai was a key player in smuggling weapons to Hamas militants in the Gaza Strip. It is believed he may have been carrying out a planned arms deal at the time of his death.
