Kenyan fighter jets have launched two air strikes against militant Islamist group al-Shabab in neighbouring Somalia.

The warplanes had targeted two camps in the Gedo region, used by al-Shabab to cross into Kenya, the spokesman added.

This will be Kenya’s first response to an al-Shabab assault which left 148 people dead at Garissa University last week.

President Uhuru Kenyatta had vowed to respond to the attack “in the severest way possible”.

Kenyan army spokesman David Obonyo told the press that the military had responded to “threats” by launching the air strike on Sunday night in the remote region.

“We targeted the two areas because according to information we have, those [al-Shabaab] fellows are coming from there to attack Kenya,” he said, in reference to Thursday’s massacre.
