DUBAI, United Arab Emirates — The head of the United Arab Emirates' civil aviation authority says investigators do not believe an explosion caused the September crash of a UPS plane in Dubai but are taking seriously a claim by Yemen's al-Qaida group that it brought down the plane.
Saif al-Suwaidi told The Associated Press Saturday that authorities "are investigating all possibilities," including the claim from al-Qaida in the Arabian Peninsula.
He reiterated that there is no evidence of an onboard explosion and says "a terror act is an unlikely cause."
But he says investigators aren't ruling it out.
Yemen's al-Qaida offshoot claimed responsibility Friday for last week's international mail bomb plot as well as the September crash of the UPS cargo plane.
