Reporting from Bogota, Colombia — Even as the government struggled to get emergency relief to thousands of flood victims, torrential rains continued to batter northern Colombia on Wednesday, adding to the misery caused by one of the worst natural disasters in this nation's modern history. Weeks of rainfall — and the breach of an important canal levee — has caused flooding that has killed 257 people and affected more than 1.9 million residents, or nearly 5% of the population. An exact count of those left homeless by water damage in several parts of Colombia was unavailable, but the total is believed to be in the tens of thousands.

In one town alone, Campo de la Cruz, 18,000 residents have been left homeless. Read more here. Semana International delivers news about Colombia in English. Find more in our home.
