A school in Kabul's Shia Hazara neighbourhood saw three explosions on Tuesday. Police said that six people were dead and 11 injured. Hospital staff said that 14 people have been wounded.
The spokesman for Kabul's commander Khalid Zadran told Reuters that three blasts had taken place in a high school and there were some casualties to Shia people. The ethnic and religious minority is frequently targeted by Sunni terrorist groups like Islamic State.
No organisation has claimed responsibility for the attack yet. International officials and analysts have been saying the risk of a resurgence in terrorism remains in Afghanistan despite the Taliban claiming they have secured the country.
Taliban took power back from the US-backed government in August last year and has been implementing strict laws across the country. The regime has met with smaller protests frequently.
Last week, Pakistan's aircraft were seen bombing the Spera district of the southeastern Khost province in Afghanistan. The attack killed at least 60 civilians. The foreign office of Pakistan has neither confirmed nor denied the attacks.
Zabiullah Mujahid, Afghanistan's deputy minister of information and culture, on Sunday said that Pakistan should not test the patience of the Afghan people. The chief spokesperson of the Taliban, he said that the ruling government is trying its best to resolve the issue with the neighbouring country through diplomatic channels and negotiations.
Pakistan has claimed that its security forces are being attacked from Afghanistan and the Taliban needs to take action against the perpetrators. The Foreign Ministry in Islamabad stated that terrorists are using Afghan soil to carry out such activities.
