NAIROBI, Kenya (AP) — Kenya's military says it's killed 10 rebels from the al-Shabab extremist group in an ambush in Kenya's south where several soldiers have died from roadside bombs.

Three soldiers were wounded in the attack in Taksile, north of Pandaguo, said military spokesman Col. Paul Njuguna in a statement.

In the past three months at least 24 soldiers have been killed by roadside bombs planted by al-Shabab which the military is fighting near the Somali border.

Al-Shabab, which is allied to al-Qaida, has vowed retribution on Kenya for sending troops to Somalia in 2011. Kenya's military attack comes days after the U.S. put pressure on the militants in Somalia with an airstrike. The U.S. Africa command said in a statement Friday that the airstrike is estimated to have killed 18 militants.
