NAIROBI, Kenya (AP) — Kenya is marking one year since four gunmen stormed the upscale Westgate Mall in Nairobi, killing 67 people.
A memorial plaque with names of the victims has been unveiled at a forest on the edge of the city where people hike. Later, a candlelight vigil will be held at a museum.
Police have increased their presence in public places such as churches, supermarkets and malls.
Police chief David Kimaiyo asked residents Saturday to be "extra vigilant" of attacks in the coming week. Kimaiyo said police had doubled patrols.
Al-Shabab militants from Somalia claimed responsibility for the mall attack saying it was retribution for Kenya's troop presence in Somalia.
More recently, al-Qaida-linked al-Shabab vowed to avenge the death of their leader killed in a U.S. airstrike earlier this month.
