The attack on Nairobi's DusitD2 hotel complex started around 3 p.m. on Tuesday, police said. The complex in downtown Nairobi is home to bars, restaurants, offices, and banks.
DusitD2 is part of an international hotel complex, and the Nairobi branch has five stars. Here's what the lobby looks like.

Meanwhile, civilians ran for their lives.
These women on higher floors climbed out the window to escape.
Witness Lucy Wanjiru told The Associated Press that she saw a woman on the ground floor get shot. She hid in a bathroom with several other people, and stayed on the phone with her friend overnight. Here, security forces help civilians flee.
Elsewhere in the complex, civilians also hid in a line behind a member of the Kenyan security forces.

Footage of the attack might have revealed a secretive US Navy mission. This still shows a woman escaping while a masked man wearing a US military-style backpack with a patch used by the US Navy SEAL Team 3 stands guard.
The attack lasted 20 hours, until Wednesday morning. People were still trapped inside the hotel as dawn broke on Wednesday morning, Reuters said.

The Somali Islamist militant group al-Shabaab claimed responsibility for the attack on Tuesday. The group often targets Kenya because the country sends troops to help protect the Somali government.
It's not clear how many militants took part of the attack. Surveillance footage from various angles showed there were at least four, Reuters reported.
14 people died in the attack, the Kenyan government said. They included 11 Kenyans, an American, and a Briton, Reuters reported, citing morgue staff. Here, a funeral van arrives at the Chiromo mortuary next to the DusitD2 complex on Wednesday.

Rescue workers and journalists were also at the scene to help and document the attack. Here are some of them by a sign leading to the complex on Wednesday.
Kenyan President Uhuru Kenyatta said in a televised address on Wednesday morning that "all the terrorists eliminated," and that "14 innocent lives were lost through the hands of these murderous terrorists."
