Outrage in Pakistan over lynch mob video

A video showing two teenage brothers being beaten to death has caused outrage in Pakistan after it was broadcast on television networks.

Pakistan's Geo News aired the footage, reporting that it showed the two young men being beaten with sticks before their bodies were dragged and hanged from a nearby metal pole.

None of the dozens of people watching tried to stop the attack, not even several police, the report said.

The killings occurred on August 15 in Sialkot, a town in eastern Punjab province.

Ten people have been arrested in relation to the lynch mob. Four of those under arrest are police officers.

Al Jazeera's Rosie Garthwaite has the story. Some of these images in this report are disturbing.
