PALO ALTO Pakistans former president says anyone involved in Novembers terrorist attacks in Mumbai must be punished, AP reports.

Former President Pervez Musharraf offered his thoughts on combating terrorism and Islamic extremism during a talk Friday at Stanford University.

While calling for punishment for those involved in the attacks, Musharraf also warned that 'hysteria' over the deadly siege in Indias financial capital threatens stability on the Indian subcontinent.

The Pakistani government has arrested scores of suspects after an investigation linked the attacks to a Pakistan-based militant group. But many Indian officials say not enough is being done to bring the perpetrators to justice.
