'Terror attack' underway at upscale Kenya hotel, say police, as armed men set off explosions and open fire

An upscale complex in Kenya's capital is under attack, with an explosion and heavy gunfire.



Witnesses and police at the Nairobi complex - which includes a large hotel known as DusitD2, banks and offices - are calling it a terror attack.



Several vehicles are burning while people are being rushed and carried from the scene. One man came out covered in blood as nearby university students were evacuated.



Four ambulances and a fire truck arrived at the scene as fleeing office workers said colleagues were still huddled under their desks.
