Home Secretary will spend more,on cargo security

Home Secretary Theresa May has pledged to review air freight security after bombs were found on two cargo jets in the UK and Dubai.

Prime Minister David Cameron said the device discovered in the UK was designed to go off on the aircraft.

Mrs May said: "Certainly, we have to look at our processes of searching and how we detect these devices."

A female medical student has been arrested in Yemen on suspicion of posting the bombs bound for the US.

Referring to the bomb uncovered in the UK, Mrs May told BBC One's Andrew Marr Show: "The crucial thing is we did find it and we were able to take action on it.

"What we have done is taken action in relation to future unaccompanied freight from the Yemen which would either be coming into the UK or through the UK, and banned that freight."
