About 10 people have been killed in an attack by a gang of armed men on an upscale shopping centre in the Kenyan capital Nairobi.
Reporters at the Westgate Mall, in the affluent Westlands area, said they had seen at least 10 bodies – though officials have not given an exact death toll.
Gunmen threw grenades and then opened fire in the attack.
Nairobi police chief Benson Kibue said it was a terrorist attack and there are about 10 terrorists involved, as gunfire continues to be exchanged.
Large pockets of people trapped inside the centre came streaming out over the course of an hour. At least half a dozen were bloodied, and many clutched small children.
Shopping centre guards used trolleys to wheel out several wounded children and at least one man.
Rob Vandijk, who works at the Dutch embassy, said he was eating at a restaurant in the shopping centre when attackers lobbed hand grenades inside the building. He said gunfire then burst out and people screamed as they dropped to the ground.
Manish Turohit, 18, says he saw gunmen with AK-47s and vests with hand grenades on them inside the centre. He escaped after hiding in the parking garage for two hours.
A group of people remain in hiding inside.
Some of those running from the scene said the attack may have been a bank robbery gone wrong.
Cars were left abandoned outside the centre after the attack started around midday local time.
One witness to the attack claimed the gunmen told Muslims to stand up and leave and that non-Muslims would be targeted.
Elijah Kamau said the gunmen made the statement about Muslims as they began their attack at the centre.
Somali’s rebel group al-Shabab vowed in late 2011 to carry out a large-scale attack in Nairobi in retaliation for Kenya’s sending of troops into Somalia to fight the Islamic insurgents.
