Peshawar school attack: How the Twitter world reacted...

Delhi: Over 130, mostly students among them, were killed on Tuesday when heavily-armed Arabic speaking Taliban suicide attackers stormed an Army-run school, shooting from classroom-to-classroom and taking several hostages using them as human shield in Pakistan's volatile Peshawar city.

A group of 8-10 suicide attackers wearing paramilitary Frontier Corps uniforms entered Army Public School on Warsak Road around 10.30 (local time) and started indiscriminate firing, Khyber-Pakhtunkhwa Chief Minister Pervez Khattak said, as per PTI.

In one of the most gruesome attacks in recent years against children anywhere in the world, the militants went from classroom-to-classroom shooting indiscriminately at the shocked students, eyewitnesses told local media.

Shocked at the horrific incident people across the world took to Twitter to condemn the attack. A look at few of the posts on the micro-blogging site:
