Bombing at mosque in Kabul kills at least 21

• The explosion appeared to be carried out by a suicide bomber, according to an eyewitness, who is a resident of the city's Kher Khanna neighborhood, where the Siddiquiya Mosque is located, per AP.
• Taliban government spokesperson Zabihullah Mujahid condemned the attack, writing on Twitter that the "perpetrators of such crimes will be ... punished for their actions."

The big picture: The Islamic State group's local affiliate has increased attacks on Afghanistan in the months since the Taliban retook control of the country.

• The Islamic State last week claimed responsibility for an attack that killed a prominent Taliban cleric at his religious center in Kabul, per AP.
• An explosion in April at a packed mosque in Kabul also killed at least 10 people and injured dozens of others.

State of play: This week marks one year since the Taliban retook control of the country. Since then, the Afghan people have borne the brunt of a collapsed economy, worsening humanitarian crisis and deteriorating human rights situation, Axios previously reported.
