Britain has announced the expulsion of an Israeli diplomat after finding evidence that Israel had forged British passports.
The 12 passports were in the names of people with dual British and Israeli citizenship and were among 27 stolen identities used by those accused of killing
Mahmoud al-Mabhouh, a member of Palestinian group Hamas in Dubai in January.
Others suspects used fake Irish, Australian or French passports, the BBC reports.
Britain's Foreign Secretary David Miliband says an investigation by the Serious Organised Crime Agency has concluded there are compelling reasons to believe that Israel was responsible for the misuse of the passports.
It is expected the diplomat to go will be the head of the London branch of Israel's intelligence agency Mossad.
Israel says there is no proof its agents were behind the killing.
