Voters in Spain's northern region of Catalonia go to the polls Sunday in a parliamentary election that is shaping up as an unofficial referendum on secession. The current Catalan president has pledged to pursue a move toward independence if re-elected.
The region, which holds 8 million people, is the country's industrial engine. Catalans are resentful that their taxes are being siphoned off for poorer regions. The prospect of secession is opposed both by the Madrid government and the European Union.
The rebel movement in the Democratic Republic of Congo has set off another humanitarian crisis. Tens of thousands of displaced villagers who fled the fighting are on the march with their belongings, and someone has to take care of them.
Into this sea of need wades Tariq Riebl, a tall 34-year-old German with a shaved head. He is the humanitarian program coordinator for the international charity Oxfam in the rebel-held city of Goma.
"Basically, what we're going to do, we have two teams," Riebl says.
