Pakistan's Hazaras fear for their lives in besieged 'ghettos'

Crowded into "ghettos" surrounded by armed checkpoints, Pakistan's Shiite Hazara minority say they are being slaughtered by sectarian militants in the southwestern city of Quetta, with authorities seemingly unable to halt the killings.

For years, hundreds of thousands of the Shiite community's members have been hemmed into two separate enclaves cordoned off by numerous checkpoints and hundreds of armed guards designed to protect the minority from violent militants.

"It's like a prison here," said Bostan Ali, a Hazara activist, about conditions inside the enclaves.

"The Hazaras are experiencing mental torture," he added, complaining the community has been effectively "cut off from the rest of the city" and "confined" to such areas.

The Shiite community's presence is particularly strong in Quetta -- the uneasy capital of impoverished Balochistan province where sectarian violence, suicide bombings, and banditry are common.

Hazaras are technically free to roam around Quetta at their will,
