DUBAI, United Arab Emirates — At least 15 more suspects carrying foreign passports were linked Wednesday to an elaborate hit squad slaying of a Hamas commander that Dubai’s police chief claims was likely carried out by Israel’s Mossad secret service.

The latest accusations by Dubai police raised the size of the alleged assassination team to at least 26 and further expanded the investigation’s international web – now stretching from an American bank to European capitals and Australia.

The police statement also left open the possibility the probe could widen and investigators were ”not ruling out the possibility” of more allegations.

Some of the new suspects – 10 men and five women traveling on British, French, Irish and Australian passports – were allegedly part of ”logistical support” teams that staked out Dubai for months before the Jan. 19 slaying of Mahmoud al-Mabhouh, one of the founder’s of Hamas’ military wing.
