Islamabad, Aug 1 (IANS) At least two children were killed and three other people were injured Monday in a blast in Pakistan’s Quetta city, Xinhua reported.

Urdu TV channel Samaa said the blast took place around 11 a.m. at a fruit market in Hazaar Ganji area of Quetta, capital of Balochistan province.

The bomb was planted in a garbage heap at the fruit market. It went off when the two children were searching for food in the garbage heap, witnesses said.

Police arrived at the scene shortly after the blast and cordoned off the site to search for other possible explosives.

No group has claimed responsibility for the attack.

Quetta has seen a series of attacks over the last couple of days. On Saturday, at least 13 people were killed when gunmen opened fire indiscriminately at a vehicle carrying Shiite Muslims.

A day earlier, seven Shiites were reportedly shot dead while heading to Iran to visit religious places. Banned group Lashkar-e-Jhangvi claimed responsibility for the attack, saying it revenge for the murder of a Sunni scholar who was killed in firing.
