Pakistan attacks in Quetta and Bara kill 15

At least 15 people have been killed in two separate attacks in Pakistan.

Eight people died when a bus carrying pilgrims was hit by an explosion in Quetta, Balochistan.

Earlier in the day a roadside bomb killed seven members of the Pakistani security forces in Bara, close to the border with Afghanistan.

Both regions have seen numerous attacks in recent years, with a number targeting Balochistan's Shia minority.

The bus attack in Quetta saw a vehicle carrying pilgrims between the city and Iran hit by either a bomb or a rocket.

A similar attack took place on 18 June in Quetta, claiming the lives of four students on a bus.

Police said they suspected Sunni militants had carried out the latest attack, which injured more than a dozen passengers.

The explosion which killed members of the paramilitary Frontier Corps in Bara was the third such attack in the past week.

Iqbal Khan, a government official, said the attack occurred as a convoy passed through a bazaar in Bara.

Pakistan's military is engaged in a long-running battle against militants in the tribal areas around Bara, including the Taliban and armed groups who support them.
