Pope Francis says he is "deeply pained" by "the gigantic avalanche of mud" in Colombia that has caused scores of deaths and injuries.

The Pope called attention to the tragedy during his Angelus blessing Sunday on a visit to the northern Italian region of Emilia Romagna, which was struck by a pair of earthquakes that killed 28 people five years ago. The region has largely been rebuilt.

Francis said he was praying for the victims in Colombia and offered thanks to those helping with the rescue efforts, the Associated Press reports.
