An explosion at a mosque in the Afghan city of Herat has killed at least 20 people and injured dozens more.
The blast, which struck the Jawadia mosque, coincided with evening prayers at around 20:00 local time (15:30 GMT).
One doctor told the Associated Press news agency that 20 bodies had been transported to his hospital.
Officials said one attacker was a suicide bomber, and a second had been armed with a rifle. Both are dead, a local police spokesperson told AFP.
