From The National:

The Israeli prime minister, Benjamin Netanyahu, will be at the top of Dubai’s wanted list if the Israeli foreign intelligence service Mossad is proven to be behind the killing of a senior Hamas official, the Dubai Police chief said yesterday.

Lt Gen Dahi Khalfan Tamim told The National that “Benjamin Netanyahu, the Israeli prime minister, will be the first to be wanted for justice as he would have been the one who signed the decision to kill [Mahmoud] al Mabhouh in Dubai. We will issue an
arrest warrant against him.”

He did not, however, assert that Mossad was definitively responsible for the killing; Hamas has accused the Israeli agency of killing Mr al Mabhouh.

The website of Ireland’s Evening Herald reports:

Members of a hit squad who killed a top Hamas military commander used Irish passports to enter and leave Dubai, it’s been claimed.

The suspected Israeli hit team, including at least one woman, entered the United Arab Emirates using Irish documents, police authorities said.

Before jumping to any conclusions about the nationalities of the assassins in Dubai, it’s worth remembering that when Mossad agents attempted to murder Hamas’ political leader Khalid Meshaal in Jordan in 1997, the Israelis were using Canadian passports.
