Police in Kenya say they have beefed up security after several European countries warned of the risk of possible attacks and urged their nationals to avoid public places. Al Jazeera reports that heavily armed officers were seen on Friday patrolling the streets of the capital, Nairobi, as security was boosted outside key government offices, five-star hotels, private buildings, and shopping centres. While the National Police Service assured the public that “security in the country ha[d] been scaled up through different policing operations”, they nonetheless urged the public to “remain vigilant and report any suspicious activities”.
