British media say the government plans to expel an Israeli diplomat because of allegations that Israeli agents used fake British passports in the killing of a Palestinian militant commander in Dubai.
Britain's Foreign Office declined to comment on the reports but said Foreign Secretary David Miliband will make a statement on the issue in parliament later Tuesday.
Dubai has accused Israel's Mossad spy agency of assassinating Hamas commander Mahmoud al-Mabouh at a hotel in the emirate in January. Authorities say the assassins entered Dubai using fake passports and stolen identities of British, Irish, French, German and Australian nationals.
The International police agency Interpol has published a list of 27 people wanted by Dubai authorities in the killing. Israel has said there is no proof that it was involved.
