Photos show guests make a harrowing escape from 5-star Nairobi hotel in 20-hour terrorist attack that killed 14

At least 14 people are dead after militant gunmen stormed a luxury hotel in Nairobi, Kenya, on Tuesday afternoon.

The siege stretched for some 20 hours into Wednesday morning, with some 700 civilians evacuated, according to Reuters.

Kenyan security forces have now had "all the terrorists eliminated," Kenyan President Uhuru Kenyatta said on Wednesday. He did not specify how many attackers there were.

The Somali Islamist al-Shabaab militant group, which has attacked Kenya before, claimed responsibility for the attack.

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.
