Al-Shabaab claims responsibility for attack that kills 36 in Kenya

Islamic extremists killed 36 non-Muslim quarry workers in northern Kenya early Tuesday, prompting Kenya's president to announce a security shakeup Tuesday, firing his Interior Minister and accepting the resignation of the national police chief.

PresidentUhuruKenyatta named an opposition politician and retired army general, JosephNkaissery, to be the new Interior Minister, in charge of security. Police Chief DavidKimaiyoresigned, citing personal reasons.

Public pressure had been mounting for the two officials to be replaced following a string of extremist attacks.

• Canadians with alleged terrorist links
• Somalia's al-Shabaab kills 28 non-Muslims in Kenya
• Al-Shabaab fighters spared Muslims, Somali speakers in deadly attack

The Tuesday killings happened at a quarry in Mandera County near the border with Somalia and the attackers escaped. The attackers singled out the non-Muslims and killed them, similar to an extremist attack on a bus 10 days ago.

50 attackers

The killings were claimed by al-Shabaab, which has been battling for years to establish hard-line Islamic rule in Somalia.

At the quarry, a group of about 50 heavily armed men walked into the camp at 12:30 a.m. as the workers were sleeping and fired warning shots, said Peter Nderitu, who works at the quarry.

Nderitu said when he heard the shooting he ran and hid in a trench from where he could hear his colleagues being asked to recite the Shahada, an Islamic creed declaring oneness with God. Then gunshots followed. He only rose from his hiding place two hours later when he was sure there was no more movement, he said. The bodies of his colleagues were in two rows and nearly all had been shot in the back of the head, he said.

The quarry camp is in the Koromey area on the outskirts of Mandera town.

Non-Muslims targeted before

Al-Shabaab spokesman Sheikh Ali Mohamud Rage said the latest attack was a response to Kenya's troop presence in Somalia and alleged atrocities committed by the Kenyan army there, such as a recent airstrike. Al-Shabaab claimed the airstrike killed innocent people and destroyed their property. The Kenyan government said the airstrike was in response to a Nov. 22 al-Shabaab attack on bus passengers in Mandera County that left 28 people dead.

In that attack, the non-Muslims were also separated from other passengers and shot dead.

About 100 non-Muslims last week sought refuge at the army base in Mandera, demanding that the government evacuate them.

President Uhuru Kenyatta's chief of staff, Joseph Kinyua, attempted to persuade non-Muslim from leaving Mandera County, whose population is predominantly Kenyan Muslims of Somali origin. Those who wanted to be evacuated argued that they cannot stay because governor himself is not safe. Mandera Gov. Ali Roba survived an improvised explosive device attack on his vehicle on October 15.

The quarry attack came hours after a hotel in Wajir, also in northern Kenya, was hit by a grenade and gunfire, killing one person and wounding 13, said police.

Attacks began in 2011

Al-Shabaab has vowed to attack Kenya for sending its troops into Somalia to fight the rebels. The Kenyan military was deployed to Somalia in Oct 2011. Since then Kenya has experienced a series of explosive and gun attacks blamed on the militants.

"I have been saying for a long time that these terrorists want to create chaos in the country by creating divisions between Muslims and Christians," said Mandera County Senator Billow Kerrow.

Kerrow said al-Shabaab is also trying to fuel tribal animosity by choosing to attack other tribes and leaving out the Kenyan Somali community who are the majority in Mandera County.

"I am worried that this may get out of hand. They can be so emboldened because they are meeting no resistance and decide to take over a town," Kerrow said.

He said despite the central government's claims that it has increased the police and army presence in the county, there is a lack co-ordination and commitment to tackle insecurity in Mandera.

President Uhuru Kenyatta has been criticized for not cutting short a four-day official trip to Abu Dhabi, after 28 people were killed in the bus attack. Public anger increased after pictures emerged on social media appearing to show Kenyatta in a selfie at a social event and reports from media in the United Arab Emirates that he was attending Formula 1 championships instead of addressing the security crisis at home.
