Dubai's police chief says he is almost certain Israel was involved in last month's assassination of a senior Hamas official.

Dahi Khalfan Tamim says, if proven, an arrest warrant should be issued for the man in-charge of Mossad, the Israeli spy agency.

Robert Fisk is the Middle East correspondent for the British newspaper The Independent.

He says if Israel is behind the assassination, then Tel Aviv could find itself in a diplomatic crisis with some of its European allies.
