9/11 tribunal: Victims' families seek justice in Cuba

Relatives of some of the victims of 9/11 have arrived in Cuba, ahead of the military tribunal of the man accused of masterminding the attacks.

Khalid Sheikh Mohammed and four other men are due to be arraigned at the tribunal at Guantanamo Bay. An earlier attempt to prosecute them was halted three years ago when President Barack Obama tried to shut Guantanamo down.

New rules for Guantanamo trials have been introduced since then, including a ban on evidence obtained under torture.

Mary Henwood, Tara Henwood-Butzbaugh and Edward Bracken all lost family members in the 2001 attacks.
