Colombia paramilitaries spread fear

For decades, Colombian citizens have been caught in the middle of turf battles between leftist guerrilla groups and right-wing paramilitaries.

In 2006 the largest of those right-wing groups – the United Self Defence Forces of Colombia – was officially demobilised and disbanded after striking a deal with the government.

But now there are concerns that remnants of these groups have joined forces, fuelled by a surge in drug trafficking, and are presenting a new threat.
