Charges against '20th hijacker' to be dropped
The US government has called for all charges against alleged September 11 plotter Zacarias Moussaoui to be dropped as part of a legal move to stop him speaking to al Qaida prisoners.
Moussaoui wants to question three al Qaida suspects who could give evidence to prove he was not involved in the terror attacks which killed more than 3,000 people two years ago.
