VALLETTA, Malta -- Two Libyan men have been arraigned in a Maltese court on charges of hijacking a domestic Libyan flight to the Mediterranean island of Malta.

Defendants Moussa Saha and Ahmed Ali each entered pleas of innocent and wore bulletproof vests in their appearance Sunday. They face up to life in prison.

The hours-long hijacking standoff Friday at the airport near Luqa ended peacefully after negotiations. Those on board the hijacked Afriqiyah Airways plane returned to Libya on a different plane Saturday.

Other charges include possession of imitation weapons, using violence against a person on a flight, holding people against their will, making threats of violence and attempting to cause financial or economic instability to a government.

Afriqiyah Airways said the hijackers wanted to go to Rome but ended up in Malta due to fuel limitations.
