The government in Dubai has issued pictures of 11 "agents with European passports" that it suspects of involvement in the assassination of a top Hamas official last month.
Mahmoud al-Mabhouh was murdered in his hotel room in Dubai on 20 January.
Hamas, the Palestinian Islamist movement, accused Israeli agents of killing him. Reports said he was in Dubai to buy weapons for the organisation.
Dubai's police chief said six of the suspects had British passports, three were Irish, one French and one German.
The passports are believed to be fakes.
