Kenyan security forces have arrested 28 aliens from Somalia in Balambala region, Garissa County in northeast Kenya as authorities tightened patrols along the porous border.

Garissa County Commissioner James Kianda said the group, consisting of 11 women and 17 men, were traveling aboard a hired private vehicle.

Kianda said members of the public informed the police, who quickly rushed to place and found the stranded aliens after their vehicle developed mechanical problem.

"The aliens decided to use the Balambala-Garissa route instead of the Dadaab-Garissa one to evade a massive security operation on the route by Kenya Defence Forces (KDF) and police. But fortunately members of the public informed us of their presence,” Kianda said.

He said that the aliens, who did not have any paper documentation, will be locked at the Garissa police station before being arraigned in court Friday to answer to charges of being in the country illegally.
