A suicide bomb attack on a gathering of religious scholars in the Afghan capital, Kabul, has killed at least 43 people, officials say.

At least 83 more were injured as the clerics met at the Uranus hall to mark the birthday of the Prophet Muhammad. It is one of the deadliest attacks in Kabul in recent months.

No-one has admitted responsibility for the blast, but the Islamic State group has said it was behind most of the recent deadliest attacks.

Continuing attacks by the Taliban have also stepped up pressure on security forces.

Basir Mujahid, a spokesman for Kabul police, said: “Hundreds of Islamic scholars and their followers had gathered to recite verses from the holy Koran to observe the Eid Milad-un-Nabi festival at the private banquet hall.”

A manager at the hall said the suicide bomber blew himself up in the middle of the gathering.

The Islamic State group said it was behind two attacks in Kabul in August that killed dozens of people. Dozens were also killed across the country as voters cast ballots in the nation’s parliamentary elections in October. However, there have been recent moves to try to end decades of war.

This month, Taliban militants for the first time attended an international meeting, hosted by Russia, to discuss the matter. The Taliban’s power and reach have surged since foreign combat troops left Afghanistan in 2014. But the Islamic State in Afghanistan group, sometimes known as Islamic State Khorasan, also remains highly active.

Civilian deaths and injuries have hit record highs. Casualty figures for the conflict, which began in 2001, are the highest since the UN started keeping records in 2009.
