(Reuters) - Islamic State has claimed responsibility for an explosion at a mosque in Afghanistan's eastern Khost province that killed and wounded scores of people, its Amaq news agency reported on Saturday.

"Around 50 of the Afghan army were killed and 110 were wounded when a martyr blew himself up on Friday," the agency said.

Security officials in the area said on Friday that the blast at a mosque in an army base had killed at least 26 people and wounded 50.
