The United States has deployed more elite forces to Manda Bay in Lamu following a deadly Al-Shabaab attack.
Al-Shabaab militants raided the US Naval Base at Camp Simba on Sunday killing one serviceman and two US contractors, AFRICOM said.
The attack was the first targeting a US military base in Kenya, a close ally of Washington in the fight against Al-Shabaab.
More elite forces from the East Africa Response Force (EARF) have since arrived at the coastal town to beef up security, US said.
“The EARF provides a critical combat-ready, rapid deployment force. The EARF’s ability to respond to events spanning a vast area of responsibility provides a proven and invaluable on-call reinforcement capability in times of need,” said US Africa Command (Africom) Director of Operations Major General William Gayler in a statement.
EARF is usually stationed at strategic buildings that hosts US citizens across Africa and also offers emergency rapid responses in case of an attack.
Currently, there are almost 100 US soldiers based in Kenya. US raised her flag at Manda Bay last year as part of counterterrorism mission against Al-Shabaab.
Sunday's attack also left one Kenyan dead despite reports from Interior Cabinet Secretary Dr Fred Matiang'i that the country did not suffer casualties.
