Pakistan: Musharraf challenged

ISLAMABAD — Pakistan's fragile coalition government set itself on a collision course with the country's U.S.-backed president Saturday with a plan to strip Pervez Musharraf of his powers.

The move could create further instability in the country and is likely to heighten U.S. concerns that political infighting is taking attention away from the anti-terror fight. The Pakistan People's Party, which leads the coalition, announced a legislative package that would take power away from the presidency and return it to the prime minister.

Vargas said relatives are helping experts identify the remains and testifying in the chief prosecutor office's probe of the massacre — possibly the largest from Peru's bloody 1980-2000 conflict.
