The Taliban-led government in Afghanistan says four bomb blasts in Kabul and Mazar-e Sharif have killed and injured more than a dozen people.
A spokesman for the Taliban's Interior Ministry, Abdul Nafee Takoor, told RFE/RL that an explosion ripped through evening prayers at a mosque in Kabul, killing two worshipers.
The bombers also were killed, and 10 people were injured.
The Kabul Emergency Hospital said it received 22 victims of the mosque bombing, including five dead. There were no further details on the blast that struck the Hazrat Zakaria Mosque in the city's central fourth district, according to Khalid Zadran, a Taliban police spokesman in Kabul.
Though there was no claim of responsibility, the explosion bore the hallmarks of Islamic State-Khorasan, the regional affiliate of the Islamic State (IS) group.
Meanwhile, the Interior Ministry said that a number of people were killed and wounded in a series of bomb blasts in Mazar-e Sharif, the provincial capital of the northern province of Balkh.
Nine people were killed in three bombings that took place after devices were placed inside minivans, according to Mohammad Asif Waziri, a Taliban-appointed spokesman in Balkh Province.
The IS group's local affiliate claimed responsibility for the minivan bombings.
The claim of responsibility was posted on the Sunni militant group's Aamaq news agency. The statement said IS targeted three minivans with improvised explosive devices.
