KABUL (Reuters). – A powerful explosion has killed over 50 people after Friday prayers at a Kabul mosque. It is the latest attack on civilian targets in Afghanistan in the Muslim holy month Ramadan.

According to Besmullah Haibib, deputy spokesperson for the interior ministry who stated that the official death toll of 10 was confirmed, the blast struck the Khalifa Sabib Mosque west of capital.

This attack occurred as Sunni Muslims gathered at the mosque after Friday prayers to a congregation called Zikr. It is an act of religious remembrance that some Muslims practice but some Sunni extremists consider heretical.

Sayed Fazil, head of the mosque said that someone believed to be a suicide bomber was present at the ceremony. He then detonated explosives.

According to him, “Black smoke rose, spread all over, dead bodies everywhere,” Reuters reported. He also said that his nephews were also among the dead. “I survived but I lost my dear ones.”

Mohammad Sabir, resident said that he saw wounded persons being taken into ambulances.

He stated, “The blast I heard was extremely loud. It made my ears ache.”

According to a health source, hospitals have received 66 bodies dead and 78 injured people thus far.

The attack was condemned by the United States and United Nations Mission to Afghanistan. They said that it was part of an increased violence against minorities over recent weeks.

Mette Knudsen is the U.N. Secretary General’s special deputy representative for Afghanistan. She stated that “no words can condemn this deplorable act.”

Kabul’s Emergency Hospital stated that 21 people were being treated and that two more had died. An employee at another hospital caring for attack patients stated that it has received around 49 patients as well as five bodies. The source said that ten of these patients were critically ill and nearly 20 were admitted to the burns unit.

Zabihullah Mojahid, a spokesperson for the Taliban’s ruling party, issued a statement in which he condemned the explosion and promised that the perpetrators will be punished.

At the time, it was unclear who was to blame.

In the last weeks, hundreds of Afghan civilians died in explosions.

The Kabul attack on April 15th left more than 100 people wounded. On Friday, April 27, the latest attack took place in Kabul. This is the day Muslims are fasting and the week before Eid.

Although the Taliban state that they have secured the country and eliminated most of the Islamic State’s local affiliates since their August takeover, analysts and international officials believe there is still a risk of militant resurgence.

Although most of the attacks were directed at the Shi’ite minority, Sunni Mosques have also been targeted.

On Thursday night, bombs detonated aboard two vans that were carrying Shi’ite Muslims to Mazar-e-Sharif. The blasts killed at least nine persons. A blast ripped through the Sunni mosque in Kunduz last Friday during Friday prayers, killing 33.
