Militant Group Attacks Kenyan Border Town

The same extremist group that took over a Nairobi mall attacked a security post near the Somali border Thursday and killed two police officers, while promising the violence would continue until Kenyan troops were withdrawn from Somalia.

The leader of the Somalia-based al-Shabab, Ahmed Godane Shaykh Mukhtar Abu Zubayr, warned the Kenyan public there was no way they could "withstand a war of attrition inside your own country," in a new statement posted on the Internet late Wednesday.

"Make your choice today and withdraw all your forces,..." Godane said. "Otherwise be prepared for an abundance of blood that will be spilt in your country, economic downfall and displacement."

The early morning attack on the town of Mandera was the second by al-Shabab militants following the bloody four-day standoff at the Westgate Mall that ended Tuesday in which at least 67 people were killed.

Regional police chief Charlton Mureithi said in addition to the two police officers killed, three others were injured and 11 vehicles destroyed in Mandera.

Wednesday night, militants attacked the border town of Wajir. One person was killed and four wounded after a gunman opened fire and threw grenades.

Such attacks occur regularly but have taken on new significance following the Westgate Mall attack.

In his statement, Godane said the mall attack was not only directed at Kenya, but was also "a retribution against the Western states that supported the Kenyan invasion and are spilling the blood of innocent Muslims in order to pave the way for their mineral companies."

Forensic experts from around the world, including the U.S., Britain and Germany, continued their work Thursday reconstructing what is now considered a crime scene, carrying out fingerprint, DNA and ballistic analysis, said police spokeswoman Gatiria Mboroki.

She said she had no details on what the experts had found so far in the bullet-scarred, scorched mall and that their work was expected to take a week.

Washington is providing technical support and equipment to Kenyan security forces and medical responders, said U.S. Ambassador Robert Godec. The U.S. is assisting the investigation to bring the attack's organizers and perpetrators to justice, he said Wednesday.

At least 18 foreigners were among those killed when the militants entered the Westgate Mall on Saturday, firing assault rifles and throwing grenades, including six Britons and citizens from France, Canada, the Netherlands, Australia, Peru, India, Ghana, South Africa and China.

In addition to those killed at the mall, another 175 people were injured, including more than 60 who remain hospitalized.

Morgue officials in Nairobi have been preparing for a large influx of bodies still in the mall. Officials have told The Associated Press that the shopping center could hold dozens more bodies.

Authorities have said at least five al-Shabab attackers were killed and another 11 suspects have been taken into custody.

In his statement, Godane said only that "some" of his fighters had been killed, possibly suggesting that others escaped.

A gaping hole in the mall's roof was caused by Kenyan soldiers who fired rocket-propelled grenades inside, knocking out a support column, a government official told The Associated Press. The official, who insisted he not be identified because he was sharing security information, said the soldiers fired to distract a terrorist sniper so hostages could be evacuated.
