Kenyan President Uhuru Kenyatta on Friday met with the country's top security chiefs amid warnings by foreign embassies of an imminent terror attack.

The meeting was attended by among others, the Interior minister Fred Matiang'I, Interior Principal Secretary Karanja Kibicho, Head of Public Service Joseph Kinyua as well as regional police chiefs.

The French embassy in Nairobi on Thursday warned its nationals of a "real risk" of places frequented by foreigners, such as restaurants, hotels and shopping centers, being targeted in the coming days.

German, Dutch and U.S. embassies also warned their citizens in the country to remain vigilant.

In response, Kenya's National Police Service said security had been beefed up to deter any threats.

"The National Police Service assures the public that security in the country has been scaled up through different policing operations," it said in a statement.

"We urge the public to remain vigilant and report any suspicious activities."
