Blast in Kabul kills 8

The IS militant group on Friday claimed responsibility for a deadly blast in Afghanistan's capital Kabul.

The Afghan police said at least eight people were killed and 18 wounded in the blast in a Shi'ite residential area.

"The explosion happened in a crowded place," said Khalid Zadran, the city's police spokesman.

The IS affiliate operating in Afghanistan since 2014 is seen as the country's most serious security challenge since the Taliban took control of the country in August last year.
