Four people were killed when a storm struck the western city of Dolores on Friday and three others were later found to have died when trying to cross flooded rivers in the region, according to a new government toll released today.
President Tabare Vazquez declared Sunday a day of national mourning.
"We are going to rebuild Dolores," he said, in comments broadcast on the radio.
Countless buildings were destroyed in Dolores, an AFP reporter in the town saw.
The National Emergency System said on Sunday that floods caused by heavy rain had forced more than 2,000 people to abandon their homes after rivers burst their banks.
