The US government has warned its citizens in Kenya of a possible terror attack in the capital Nairobi.

Through its embassy in Nairobi, the US flagged high traffic areas frequented by foreigners and tourists in Kenya's capital, Nairobi, and elsewhere in the country as targets for the terror groups.

The embassy asked US citizens to exercise vigilance at locations frequented by tourists and foreigners, to review their personal security plans, be conscious of their surroundings and to monitor local media for updates.

"Terrorist groups could attack with little or no warning, targeting hotels, embassies, restaurants, malls and markets, schools, police stations, places of worship and other places frequented by foreigners and tourists,” the US statement said.

The US embassy acknowledged security measures that the Kenyan government put in place, including counterterrorism patrols.

This comes barely a month after the US Embassy in Tanzania issued a security alert to its citizens over what it termed as possible attack.

But the government of Tanzania allayed fears of impending terrorist attack threats in the country’s commercial capital, Dar es Salaam, and other areas.

In a notice dated January 25, the US Embassy in Tanzania claimed that the terror groups were planning to carry out an attack in high traffic areas frequented by westerners in Dar es Salaam and elsewhere in the East African country.

On January 25, the US embassy in Tanzania published a security alert regarding high traffic areas frequented by Westerners in Dar es Salaam and elsewhere in Tanzania.

The statement read: "Locations frequented by U.S. citizens and other Westerners in Dar es Salaam and elsewhere in Tanzania continue to be attractive targets to terrorists planning to conduct attacks.

"Terrorist groups could attack with little or no warning, targeting hotels, embassies, restaurants, malls and markets, police stations, places of worship, and other places frequented by Westerners.”

In its response, the country’s police force noted that any major threats that would worry citizens are under controlled. In addition, the police urged citizens to report whenever they find something suspicious or when they doubt someone due to his or her behaviour.
