US forces killed 60 al-Shabab militants in an airstrike last Friday on Harardere in central Somalia, the US military has said in a statement that updated the figure from four.

The "precision airstrike" carried out in coordination with the Somali government did not kill any civilians, the military adds.

It calls it "the largest airstrike against al-Shabab" for nearly a year.

In November last year the US said it had killed "100 terrorists".
