JOHANNESBURG, South Africa _ The Somali extremist group Shabab claimed responsibility Tuesday for an attack that killed at least 12 non-Muslims sleeping in a hotel in the northern Kenya town of Mandera near the Somali border.
The attack on Bishaaro Guest House was part of a campaign to kill "unbelievers" in Kenya, the Islamist group said. The Shabab, affiliated with al-Qaida, claimed 15 were killed, while authorities put the toll at 12.
The attackers reportedly used explosives to blow open the metal front doors of the hotel before bursting in and shooting the victims.
Hours later, the group claimed responsibility for a major attack in Somalia when a suicide bomber with a truck carrying explosives slammed into the gate of a military base of the U.N.-funded African forces fighting the Shabab, AMISOM.
The base in Beledweyne, north of the capital, Mogadishu, was occupied by soldiers from Djibouti, an important U.S. ally in the volatile Horn of Africa. Gunmen then attacked the base, a strategy successfully used in past attacks, including an attack against Kenyan forces in El Adde, southern Somalia, in January, which killed about 180 soldiers.
Authorities have not announced how many soldiers died in the Beledweyne attack Tuesday.
The Shabab group has repeatedly targeted Kenya because of the country's military role in Somalia, as well as other countries involved in the force, including Uganda. Kenya invaded Somalia in 2011 after a spate of attacks and kidnappings in northern Kenya.
Eleven men and one woman were killed in the early morning guesthouse attack. Ten of those were teachers from other parts of Kenya, in Mandera to stage plays for students about books that have been set as part of the high school curriculum, local officials told Kenyan media.
One survivor, teacher Veronica Wambui, told Kenya's Nation Media she heard explosions around 2:30 a.m. before attackers entered and shot her colleagues.
She was shot at three times, but managed to hide in a storeroom with others. Another blast went off, and part of a wall collapsed on her and others.
"I could see the lights from the (flashlight) when they were checking out the room but the collapsed wall had covered me," Wambui told The Associated Press later, speaking from the hospital. She had a bullet wound in her hand and injuries to her legs.
It was the second attack in three weeks in Mandera, a volatile border town. In an Oct. 5 attack, five Christians were beheaded, with the Shabab claiming responsibility.
The Shabab, fighting the U.N.-supported Somali government, has staged several major attacks in Kenya in the past, usually questioning people to see if they were Muslims or Christians, and sparing the Muslims. Its worst attack in Kenya occurred in April 2015 at a university in Garissa, in northern Kenya, where 147 people were killed, mostly Christian students from other parts of the country. In September 2013, Shabab gunmen attacked the upscale Westgate shopping mall in the capital, Nairobi, killing at least 67 people.
The Shabab has lost a series of commanders and has seen some of its followers split off to form a faction loyal to Islamic State, but it still remains capable of carrying out devastating attacks, as well as drive-by shootings and assassinations.
