The death toll from a suicide bomb attack on a wedding party in Kabul last week has risen to 80, two senior Afghan officials said on August 21.

The initial death toll after the August 17 explosion was 63, but some of the wounded had died in hospital, said Nasrat Rahimi, an Interior Ministry spokesman.

"Seventeen others have succumbed to their injuries in hospital and over 160 are still being treated either in hospitals or at home," Rahimi said.

The Islamic State (IS) militant group claimed responsibility for the attack on a huge wedding reception at a hotel in western Kabul.

The attack was the 17th to take place in Kabul since the beginning of the year and the second deadliest one in August alone.

At least 193 people have died and nearly 900 others have been injured in the attacks.

The attack came with Washington and the Taliban reportedly nearing a deal to end the nearly 18-year war

With reporting by Reuters and dpa </s> KABUL, Afghanistan — An Afghan official says the death toll in a suicide bombing at a wedding in Kabul claimed by the local Islamic State affiliate has risen to 80. The initial death toll in Saturday’s blast was 63.

Interior Ministry spokesman Nusrat Rahimi said on Wednesday that 17 civilians have died from their wounds in recent days. He says 30 people were in critical condition after the attack.

The new toll was confirmed as the United States envoy negotiating with the Taliban for an end to nearly 18 years of fighting in Afghanistan is returning to Qatar to resume the talks with the insurgents.

Concerns are growing that the IS threat will mean little peace for Afghan civilians despite the U.S.-Taliban negotiations to end America’s longest war. </s> Kabul - The number of people killed in an Islamic State suicide bombing of a wedding hall in Afghanistan's capital Kabul has risen to 80, an official said on Wednesday.
