"We have lost five soldiers and seven others sustained injuries during the fighting. We killed 11 al-Shabab fighters and seized weapons," the commander said.

The commander said the move to attack al-Shabab came after a tip-off indicates that the militants were planning to wage offensive on Jubaland forces but they responded quickly and attacked them.
