High alert in Somalia

Aid workers in Somalia have been put on high alert after the United States killed a senior member of al Qaeda in a dramatic raid on the Horn of Africa nation.

Militants from the Somali al Shabab group with suspected links to the terror network yesterday vowed revenge against "any and all" targets with Western links after the death of Saleh Ali Saleh Nabhan.

"They will taste the bitterness of our response," one commander said.
