A Nepalese army officer from Hastings is due to appear at the Old Bailey charged with two counts of torture.
Colonel Kumar Lama, 46, of St Peters Road, is accused of inflicting severe pain or suffering when he was acting in an official capacity.
The offences are said to have taken place in 2005 at the Gorusinghe Army Barracks, Kapilvastu, Nepal.
Lama, who has served in the Nepalese Army since 1984, was in charge of the barracks at the time, during the Himalayan nation's decade-long Maoist insurgency.
The charges relate to two men, Janak Bahadur Raut and Karam Hussain.
Lama, who has indefinite leave to remain in the UK, had been serving as a UN peacekeeper in South Sudan.
He was due to return to the country after spending Christmas in East Sussex before his arrest.
