WITNESS-In search of invisible borders in central Africa

Joe Bavier has reported on West and Central Africa for four years. He joined Reuters as Kinshasa correspondent in 2006. In the following story, he describes a trip to Central African Republic's porous eastern border with Sudan in the aftermath of a wave of raids by Uganda's rebel Lord's Resistance Army.

BAMBOUTI, Central African Republic (Reuters) - "We aren't in Sudan, are we? Because we're not allowed to go to Sudan."

The question, asked by an admirably rule-abiding aid worker, made me smile. Here in this forgotten corner of Africa, where simply finding an international border requires patience and 21st century technology, who would ever know we were here?

"Still in Central African Republic," I said, looking down at the GPS on my satellite phone. "I think."

A friend and colleague once said Central African Republic has one redeeming quality -- it's easy to find on a map. After all, the directions are in the name.

But its history shows how much this poor former French colony has been a victim of that geography.

Sandwiched between some of the world's most unstable countries, it has been variously crisscrossed by marauding fighters from Democratic Republic of Congo, coup-assisting Chadian mercenaries, southern Sudanese rebels, and Janjaweed militia from Darfur.

I was in the densely forested eastern borderlands on the trail of the most recent trespassers, the Lord's Resistance Army (LRA) -- rebels from northern Uganda who are led by self-proclaimed mystic Joseph Kony and notorious for using boys as child soldiers and girls as sex slaves.
