Students and teachers protest in Pakistan after shootings

2,000 girls and boys walk out of classes accompanied by their teachers in protest after a driver was shot dead and a student critically wounded in an attack on a school bus in Pakistan on Monday.

The Swat Valley, where the attack took place, was once overrun by the Pakistani Taliban, who notoriously shot Nobel laureate Malala Yousafzai on a school bus in the same city ten years ago.

The area has seen a resurgence of militancy since the Taliban returned to power in Afghanistan last year with a spike in attacks -- mainly targeting security forces -- in recent weeks.
