On April 29, 2022, people leave the site of an explosion as a Taliban fighter stands guard in Kabul, Afghanistan. EBRAHIM NOROOZI AP KABUL - A powerful explosion killed more than 50 worshippers after Friday prayers at a Kabul mosque, the leader said, the latest in a series of attacks on civilian targets in Afghanistan during the Muslim holy month of Ramadan.
The blast hit the Khalifa Sahib Mosque in the west of the capital in the early afternoon, according to Besmullah Habib, deputy spokesman for the interior ministry, who said the official confirmed death toll was 10.
The attack came as worshippers at the Sunni mosque gathered after Friday prayers for a congregation known as Zikr - an act of religious remembrance practiced by some Muslims but seen as heretical by some hardline Sunni groups.
Sayed Fazil Agha, head of the mosque, said someone they believed was a suicide bomber joined them in the ceremony and detonated explosives.
He said that his nephews were among the dead, as black smoke rose and spread everywhere, and dead bodies were everywhere. I lost my beloved ones, but I survived. Resident Mohammad Sabir said he had seen wounded people being loaded into ambulances.
The blast was very loud, I thought my eardrums were cracked, he said.
A health source said hospitals had received 66 dead bodies and 78 wounded people so far.
The United Nations mission to Afghanistan and the United States condemned the attack, with the latter saying it was part of an increase in violence in recent weeks targeting minorities and adding that at least two UN staff members and their families were in the mosque at the time of the attack.
"No words are strong enough to condemn this despicable act," said Mette Knudsen, UN secretary general's deputy special representative for Afghanistan.
Emergency Hospital in downtown Kabul said it was treating 21 patients and two were dead on arrival. A worker at another hospital treating attack patients said it had received 49 patients and around five bodies. The source said that ten of the patients were in critical condition and almost 20 had been admitted to the burns unit.
A spokesman for the ruling Taliban, Zabihullah Mujahid, issued a statement condemning the blast and saying the perpetrators would be found and punished.
It wasn't immediately clear who was responsible.
Scores of Afghan civilians have been killed in recent weeks in attacks, some of which have been claimed by the Islamic State.

The Emergency Hospital said it had treated more than 100 patients wounded in attacks in Kabul in April. The latest attack came on the last Friday in the month of Ramadan, in which most Muslims fast, and before the religious holiday of Eid next week.
The Taliban say they have secured the country since taking power in August and have largely eliminated Islamic State's local offshoot, but international officials and analysts say there is a risk of a resurgence in militancy.
Sunni mosques have also been attacked, as many of the attacks have targeted the Shi'ite minority.
At least nine people were killed in the northern city of Mazar-e- Sharif on Thursday after two passenger vans carrying Shi'ite Muslims exploded. Last Friday, a blast tore through a Sunni mosque during Friday prayers in the city of Kunduz killed 33.
