A senior presidential aide told Yemen Post that the United States has yet to handover any evidence proving that a Yemeni national was planned to be involved in the bombing of a US airliner using an underwear bomb.

The official said that the Yemeni government expected AQAP to attempt an attack but on a different scale and with their full knowledge in cooperation with Washington.

The official said that the Yemeni government will ask Washington to handover the evidence to ensure a full investigation take place.
