3 blasts rock Quetta in Pakistan

Three explosions rocked Quetta city of southwest Pakistan today, injuring at least six persons and causing panic among residents.
Three bombs went off in an open field at Jinnah Town, Gawalmandi Chowk and an intersection at Gurdat Singh Road this evening.
Six persons were injured at Gawalmandi Chowk, police officials told the media.
Three of the injured were in a serious condition, officials said.
The explosions were heard from several kilometres away and caused panic across Quetta, the capital of Balochistan province.
No group claimed responsibility for the attacks.

Balochistan has witnessed a spike in violence ahead of the May 11 general election.

Several government offices across the province have been targeted with bombs.
On April 16, six persons were killed and about 30 injured when PML-N leader Sanaullah Zehri's motorcade was targeted with a bomb in Khuzdar district.
Zehri escaped unhurt but his son, nephew and brother died in the attack.
