Officials say Pakistani forces on Tuesday also killed four men during an operation on the outskirts of Quetta where thousands of Shias are refusing to bury the victims of last Saturday attack to secure better protection for the Shia community in the country.
Akbar Hussain Durrani, the home secretary of Baluchistan province, said that one of the masterminds of carnage was among those arrested on Tuesday.
"Those who were killed were high-profile target killers," he said.
A spokesman for the outlawed Pakistani terrorist group Lashkar-e-Jhangvi claimed responsibility for the bombing that drew global condemnations.
In a similar attack on January 10, a twin bomb explosion at a crowded billiard hall killed more than 90 people, mostly Shia Muslims, in Quetta, which is the capital of Balochistan province. Lashkar-e-Jhangvi said it carried out the bombing.
On Monday, the Pakistani Supreme Court issued summons to the Attorney General of Pakistan and Advocate General of Balochistan.
A three-judge bench of the country’s top court, led by Chief Justice Iftikhar Muhammad Chaudhry, will begin hearing the case from Tuesday.
Following the Quetta massacre, massive demonstrations were held across Pakistan and other countries to denounce the violence against Shia Muslims.
The protesters said the Pakistani government had failed to take proper action to prevent the terror attacks on the Shia Muslim community.
In Pakistan, the demonstrators shouted slogans against the government and criticized Pakistan’s security forces for failing to provide security for the country’s Shia Muslims.
Shias make up about 20 percent of Pakistan’s population of over 180 million.
