Somalia's government is warning that terrorists could strike back following the death of the leader of an Islamic insurgent group who was killed in a U.S. air strike Monday in southern Somalia.

In a televised speech Friday night, Gen. Khalif Ahmed Ereg, Somalia's national security minister, said the warning was based on credible intelligence that militants are planning attacks on key targets including medical and educational institutions following the death of Ahmed Abdi Godane.

Ereg says the government is vigilant and prepared its armed forces to prevent such desperate attempts. Godane had publicly claimed al-Shabab was responsible for the deadly Westgate Mall attack in Nairobi, Kenya almost a year ago that left 67 people dead.

President Barrack Obama confirmed Friday that Godane was killed by the U.S. airstrike.
