7/7 accused: I trained in militant camp

LONDON, England (CNN) -- A man accused of helping to plot the 2005 terror attacks on London's transport network Tuesday admitted making a trip to a training camp close to the Afghan border.

Waheed Ali, one of three men currently on trial for the suicide bombings that killed 52 people, said he made a trip in 2001 to a training camp in Pakistan's North West Frontier Province with the ringleader of the attacks, Mohammed Siddique Khan.

Ali said the mountain camp was run by Harakat ul-Mujahideen, a militant Pakistani Islamic group proscribed in the UK as a terrorist organization. He said both men learned how to fire Kalashnikovs and rocket-propelled grenade launchers, among other activities.

He said that although there were more than 100 others at the camp, people from the UK were given the best tent, as well as special food and their own trainer. "It was because they relied on the British for money," he said, according to the Press Association.

Waheed Ali is charged, along with Sadeer Saleem and Mohammed Shakil, of conspiring with Khan, Shezhad Tanweer, Jermaine Lindsay, Hasib Hussain and others unknown to cause explosions. They all deny the charges and the trial continues.
