US sends combat troops to Uganda

Barack Obama, the US president, has announced he is sending combat troops to Uganda to help efforts against rebels of the Lord's Resistance Army, who Washington accuse of grievous human rights abuses.

A force of 100 trainers and advisers will take part in the hunt for Joseph Kony, one of central Africa's most brutal rebel leaders.

Many are questioning as why the US, already involved in two long wars, would commit its forces to this mission.
