A bomb exploded outside a mosque in Kabul, Afghanistan's capital, when worshippers were going out of the premises after offering weekly Friday prayers, killing and injuring several people.

An explosion occurred on the main road near the Wazir Akbar Khan Mosque after Friday prayers, according to Kabul police spokesman Khalid Zadran.

The victims were all civilians and worshippers, he said, adding that more information regarding the casualties would be released to the media later. Taliban's security men have arrived at the blast scene and are preventing vehicles from passing through.

On Twitter, the Emergency Hospital in Kabul confirmed 14 victims, four of whom were already dead when they arrived. Eyewitnesses told local Tolo news that the explosion was triggered by a magnetic bomb.

The media outlet, however, did not provide a precise number of casualties.

So far, no group has claimed responsibility for the latest terrorist attack in the capital. However, ISIS/Daesh has in recent months increased attacks on mosques in many parts of the country, including Kabul, by accepting responsibility.
