Three children and two adults were killed in a blast on Wednesday that targeted a school bus in south-western Pakistan, with Islamabad blaming India for the attack.

Terrorists targeted the bus in the city of Khuzdar, in the restive province of Balochistan, as it took students to a military-run school, Balochistan Chief Minister Sarfraz Bugti said.

Preliminary findings suggested that it was not a suicide attack, he said at a press conference.

The dead included three young girls who were students of grades 6, 7 and 10. More than 40 students were wounded, many of them said to be suffering severe wounds.

Bugti said that his government had intelligence reports that Indian National Security Advisor Ajit Doval was planning something in Balochistan but did not expect him to target innocent children.

“After facing a humiliating defeat on the battlefield, India has resorted to despicable and cowardly acts,” the media wing of Pakistan’s military said in a statement.

“Planners, abettors and executors of this cowardly Indian sponsored attack will be hunted down and brought to justice and heinous face of India will be exposed in front of the entire world,” the statement added.

Prime Minister Shehbaz Sharif will make an emergency visit to the province where he would be briefed on the attack by terrorists, allegedly backed by India, said a statement issued by his office.

The Baloch Liberation Army (BLA), a rebel group fighting for the independence of the region from Pakistan, earlier claimed it targeted the bus, but said it was transporting the soldiers.

Islamabad claims that the BLA is backed by India.

Violence orchestrated by sub-nationalist rebels has surged in Balochistan, a region that borders both Afghanistan and Iran, and is a hub of Chinese investment and connectivity projects.

Earlier this month, India and Pakistan carried out tit-for-tat drone, missile and airstrikes targeting each other’s military installations and airbases.

The nuclear-armed rivals agreed to the ceasefire on May 10 but continue to accuse each other for terror incidents. (dpa/NAN)
