Kenyan President Uhuru Kenyatta has said that a siege by suspected Somali militants in Nairobi is over and all the attackers have been killed”.

In a TV address to the nation, Kenyatta said 14 people were killed and 700 others were safely evacuated from the complex.

“I can now confirm that the security operation at Dusit is over and all terrorists have been eliminated.

“We will seek out every person that was involved in the funding, planning and execution of this heinous act.

“We are a country governed by laws, rules and regulations – a country that embraces peaceful coexistence… I must also state that we are also a nation that never forgets those who hurt our children.”

Gunmen attacked the compound in the Westlands district of Kenya’s capital on Tuesday. The complex houses the DusitD2 hotel as well as offices.

The Somalia-based militant group al-Shabab said it was behind the attack. It is not clear how many attackers there were.

Officials originally announced the end of the siege hours after it began, but gunfire and explosions were heard again early on Wednesday.

The Kenyan Red Cross put the number of dead at 24. A US citizen is among the dead, the US State Department said, and a British citizen was also feared killed.

The attack began at about 15:00 local time (12:00 GMT) when four gunmen threw bombs at vehicles in the car park before entering the lobby, where one blew himself up, police say.

Kenya has seen a number of terror attacks in recent years – most notably in areas close to the Somali border and in the country’s capital.
