Suicide bomber hits Pakistan militant base; 23 die

PESHAWAR, Pakistan (AP) — A suicide bomber attacked the headquarters of a rival insurgent group in northwest Pakistan today, killing 23 of its supporters in an outbreak of factional fighting, an official said. Elsewhere in the Afghan border region, fighting between security forces and militants claimed the lives of 41 others, an especially deadly day that showed the level of instability 10 years after the U.S.-led invasion of Afghanistan heralded the unrest.
