Police on Sunday claimed to have foiled a major terror plot as the Bomb Disposal Squad (BDS) defused a bomb found planted at Quetta's Sabzal Road area Sunday, police sources said.

The bomb weighing 5-6 kilograms was planted under a can and spotted by locals who informed the police, the sources added.

Traffic was halted and shops shuttered as the BDS arrived on the scene soon after and defused the bomb.

Security forces have been on high alert and reinvigorated nationwide intelligence operations as the country faces a fresh resurgence in terror attacks.

At least 88 people were killed and hundreds were injured when a bomb ripped through the shrine of Lal Shahbaz Qalandar in Sehwan this month ─ the deadliest amongst a series of attacks carried out by militants in recent weeks.

In January, six Frontier Corps personnel were injured in a bomb blast claimed by the Baloch Liberation Army in the western bypass area in Quetta.

According to officials, some militants planted an explosive device on a road linking the FC firing range area with the western bypass. The bomb went off when a vehicle carrying the FC soldiers was passing through the area.
