KABUL - A suicide bomber attacked a mosque in Afghanistan's northeastern Kunduz province on Friday, killing 46 people and wounding more than 140, the state-run Bakhtar news agency reported.

Earlier, a UN agency said the blast killed and wounded more than 100 people.

The blast followed several attacks, including one at a mosque in Kabul, in recent weeks, some of which have been claimed by the Sunni Muslim militants of Islamic State

"Initial information indicates more than 100 people killed and injured in a suicide blast inside the mosque," the United Nations' mission to Afghanistan said in a tweet.

Video footage showed bodies surrounded by debris inside the mosque that is used by people from the minority Shi'ite Muslim community.

No group immediately claimed responsibility. The blast followed several attacks, including one at a mosque in Kabul, in recent weeks, some of which have been claimed by the Sunni Muslim militants of Islamic State.

The attacks have underscored security challenges for the Taliban, which took over the country in August and have since carried out operations against Islamic State cells in Kabul.
