KABUL, Afghanistan — An explosion at a Shiite mosque in northern Afghanistan on Thursday killed at least 10 people and wounded more than two dozen others, local officials said, adding to the toll of a bloody week for one of the country’s religious minorities.
The attack, during afternoon prayers at the Seh Dokan mosque in the center of Mazar-i-Sharif, one of the country’s economic hubs with a bustling downtown of alleyway shops, came just two days after several explosions ripped through a predominantly Shiite neighborhood in Kabul, the capital.
While the details of the attack at the mosque were murky, and there were fears that the death toll would climb higher, unverified videos shot inside the building showed an amount of carnage that has become all too familiar in Afghanistan over four decades of conflict.
“Up to now we have 12 dead and 35 injured. Eight of them are in bad condition,” said Dr. Gaousuddin Anwari, the director of Abu Ali Sina-e-Balkhi Hospital in Mazar-i-Sharif. Abdul Nafi Takor, a spokesman for the Interior Ministry, offered a different assessment, saying that 10 people had been killed.
A Taliban official in the province said it was unclear what caused the explosion, but the Islamic State’s affiliate in Afghanistan, known as Islamic State Khorasan, claimed responsibility for the blast, according to SITE Intelligence Group, which tracks extremist organizations.

“I was in my pharmacy when I heard the sound of an explosion,” said Nazir Samim, a resident of Mazar-i-Sharif. “I went to the mosque to help the wounded, but the Taliban did not allow me to enter.”
Around the time of the mosque blast, an explosion on a minibus in Kunduz city, the capital of the province of the same name and about 100 miles to the east, killed at least one person, said Mr. Takor. No group claimed responsibility for that attack.
On Tuesday, several explosions outside an education center and a public high school in the western Kabul neighborhood of Dasht-e-Barchi killed at least six people and wounded at least a dozen more.
The area, home to a large Hazara community, an ethnic minority that is predominantly Shiite, was frequently targeted by both the Taliban and the Islamic State over the last 20 years, when the country’s Western-backed government was in power.
Since the Taliban took control of the country in August, the hard-line Sunni religious group has tried to stay to true to its bedrock pledge of providing security to Afghans of all religious groups and ethnicities — even though it targeted some of them during the past two decades and killed thousands of Hazaras during its first tenure in the 1990s.
Despite that pledge, Shiites, especially Hazaras, have come under frequent attack, primarily from the Islamic State’s affiliate in the country, over the past eight months.
Last year, Islamic State bombings of Shiite mosques in Kandahar and Kunduz killed and wounded dozens. In the Dasht-e-Barchi area of Kabul, a series of unclaimed car bombings have regularly killed Hazaras, though in relatively small numbers.
On Monday, the Islamic State claimed it had carried out a rocket attack from Haritan, a border town roughly 50 miles north of Mazar-i-Sharif, on a military base in Uzbekistan, but the Uzbek government denied any such attack took place.
The extremist group has slowly gathered strength in recent months, despite the Taliban’s attempts to stamp out its fighters in the country’s east.
