Some 60 people have been killed in two separate attacks on mosques in Afghanistan, officials say.
A gunman entered a Shia Muslim mosque in Kabul before opening fire and detonating an explosive, killing at least 39 worshippers.
An attack on a Sunni Muslim mosque in Ghor province killed 20 people.
So-called Islamic State (IS) said it carried out the attack on Kabul's Imam Zaman mosque, but provided no evidence for the claim.
The group has previously targeted Shia mosques across Afghanistan.
The new attacks bring to at least 176 the number of people killed in bomb attacks across the country this week.
