The National reports:

Dubai authorities have asked the FBI to investigate the links between suspects in the murder of the Hamas leader Mahmoud al Mabhouth and their American-issued payment cards, an FBI source confirmed yesterday.

The investigation will seek to discover the source of the funds used in the January 19 assassination at a Dubai hotel, particularly to establish if there is a link to Israel or its intelligence agency Mossad. Thirteen of the 27 suspects used prepaid MasterCards issued by MetaBank, a regional American bank, to purchase plane tickets and book hotel rooms, according to Dubai Police.
