Somalia-based Al-Shabaab terror group has claimed responsibility for an attack that left five police officers dead in an ambush in neighbouring Kenya. One of the group's spokespeople, Sheikh Abdiasis Abu Musab, told Reuters four officers were also wounded as a police vehicle was ambushed and burned in Mandera county, on the border with Somalia.

The Islamist outfit added it will continue to carry out attacks until Kenya withdraws troops deployed to Somalia to help in the anti-terror fight.

Two of the policemen killed were burned beyond recognition in the attack, Mandera County Police Commander Job Boronjo told AP.

Ali Roba, governor of Mandera, confirmed the attack took place and claimed the presence of militants in the area "was long shared by locals".

Shabaab often targets Kenya in retaliation for the Linda Nchi military operation, which saw the deployment of Kenyan troops to Somalia to drive out the militants in 2011.

In one of its deadliest attacks, the militants killed 148 people at a university college in Garissa. The terrorists claimed the attack was carried out as the university was "on Muslim land colonised by non-Muslims".
