QUETTA: Pakistan has suspended buses carrying Shia Muslim pilgrims from travelling through its volatile Balochistan province to neighbouring Iran due to security concerns after a suicide attack killed 30 pilgrims this week, officials said on Friday.

A 700 km highway connecting the Pakistani city of Quetta and Iran, home to many Shia pilgrimage sites, has seen dozens of suicide and roadside bomb attacks claimed by radical Islamist groups.

“We have temporarily suspended the movement of buses on the highway until the security situation improves,” a senior official of the provincial government told Reuters.

Sectarian attacks are on the rise in Pakistan, where minority Shias make up about 20 per cent of the 180 million people.

Human Rights Watch says more than 400 Shia Muslims were killed in 2013, including members of the ethnic Hazara community.

On Tuesday, a suicide bomber drove his car into a bus killing 30 pilgrims and prompting hundreds of Shia Hazaras to take to the streets to protest against the violence.

“No place is safe for us. There is no alternate road. We have to travel through this ‘bloody highway’ each time we go on a pilgrimage,” said Mohammad Ismail Changazi, one protester.

Militant group Lashkar-i-Jhangvi (LJ) claimed responsibility for the latest attack.
