Al-Shabaab terrorist group captured the Somali border town of Balad Hawo near Kenya after it detonated a suicide car bomb and then stormed the military base there early Monday, the al Qaeda-linked group's spokesman told Reuters.
The group also said 24 Somali soldiers were killed but there was no independent confirmation available immediately.
Residents said the fighting was continuing Monday.
This comes as a suicide bomber killed at least four people in central Somalia on Sunday, a security source said, in an attack claimed by the Shabaab movement.
Mohamed Abdulkarim, a security official in the town of Beledweyne, 300 kilometers north of the capital Mogadishu, said the bomber "detonated himself at a tea shop in front of the regional headquarters and four people died, all of them civilians."
Thirteen others were wounded.
Witness Osman Adan said there was a "huge blast... there were several dead bodies and wounded people strewn in the area."
Shabaab militants claimed Sunday's attack, which the group said had killed six "soldiers", including three serviceman from neighboring Djibouti.
The Shabaab have sworn to overthrow Somalia's fragile government, which is kept in place with international support.
The Shabaab force was pushed out of the capital in August 2011 and lost most of its other bastions in Somalia.
But they still control vast swathes of countryside, from where they launch guerrilla operations and suicide attacks, against the capital and against local and international military bases.
