Soon after, police, security forces and rescue teams rushed to the site but angry people of the Shia Hazara community cordoned off the area and didn't allow any of them to enter and started rescue work by themselves.
The enraged people chanted slogans and pelted stones at the security personnel, saying the government machinery had failed to provide them with adequate security.
The Hazara Shias have been targeted dozens of time in Quetta over the last two years in which hundreds of people have lost their lives.
Later, high officials intervened through negotiations that convinced protesters to allow rescue teams to carry on operations at the affected site.
