Somalia had to 'host' their home tie on neutral territory - in Addis Ababa in Ethiopia - because of the long-standing conflict in the horn of Africa.
Coach James Magala felt his side played well despite the defeat but was unhappy with their lack of accuracy in front of goal.

"We will have to go into the next leg looking for goals."

In the late kick-off on Friday, The Gambia came from behind to salvage a 1-1 draw at home to Namibia.
Petrus Shitembi put Namibia ahead after 64 minutes, with an away goal which could prove vital after the two legs.
But the hosts gave themselves hope ahead of the away leg with an equaliser from captain Abdou Jammeh 14 minutes later.
The Gambia's Swansea City winger Modou Barrow did not play and will not feature in the away leg either because he wants to concentrate on his career at the English Premier League side having only just returned there form a loan spell at Blackburn.
There has been speculation that the 22-year-old asked not to be included in the squad over the selection of Omar Jagne.
Barrow said: "I am 100% disappointed with the claims that I rejected the call-ups over Omar Jagne. This is false and meant to tarnish my image."
