Bomb 'meant to explode on plane'

The Prime Minister has said he believes the device found on board a cargo plane at East Midlands airport was designed to go off on the aircraft.

Earlier, Home Secretary Theresa May said the bomb was viable and could have brought down the plane if it had exploded.

It was one of two packages from Yemen placed on board US bound cargo planes.

The authorities in Yemen have said that a female suspect has been arrested in the capital Sana.
