Islamabad: A senior minister in Pakistan's restive Balochistan province, Sardar Sanaullah Zehri escaped an attempt on his life when a powerful explosive device went off as his cavalcade was passing by near Surab in Kalat district.

Zehri, who is a provincial minister for Services and General Administration Department (SGAD) was on his way to Khuzdar from Kalat last night when an explosive device planted along the highway went off, near Anjera area, police said.

The minister escaped unhurt as the blast went off a few minutes before his convoy passed by, they said.

"The target was Sardar Sanaullah Zehri. No one was hurt in the explosion," Express Tribune quoted a police official as saying.

The paper said banned Baloch Liberation Front (BLF) outfit had claimed responsibility for the attack.

The outfit's spokesperson, who introduced himself as Duda Baloch said his organisation would target Zehri again.

A heavy contingent of police and law enforcing agencies rushed to the spot and set up a security cordon around the minister and a manhunt was mounted in the area.
