Britain's charity watchdog said on Saturday it was examining claims that several suspects in the alleged London plane plot were linked by their involvement with an aid group that raised money for victims of last year's earthquake in Pakistan. Crescent Relief London was reportedly founded in 2000 by Abdul Rauf, whose sons are suspects in the case. Rauf is being questioned by investigators in Pakistan. Abdul Rauf reportedly stepped down from the charity group's board several years ago. The Times newspaper says the aid group may have linked plot suspects in High Wycombe.
