The Taliban has claimed responsibility for a huge explosion in the Afghan capital of Kabul.
The blast occurred at around 01:25 local time on Monday (20:55 GMT on Sunday) and could be heard across the city.
Power appeared to cut off briefly in parts of the city shortly before the explosion, according to reports on social media.
An email message from Taliban spokesman Zabihullah Mujahid said insurgents had attacked that hotel with a truck bomb and claimed dozens of casualties.
Afghanistan's Tolo news agency reports that four people may be involved in the incident.
There were also reports of gunfire heard at the scene of the blast, and police and security forces later sealed off the area.
The blast comes about a week after a suicide attack on a demonstration by members of Afghanistan's Hazara communitykilled at least 80 people and wounded more than 230.
There was no official word on casualties.
