Six people drowned or were killed by falling structures over the weekend, after a torrential rain lashed Senegal, causing houses to crumble and neighborhoods to flood under the rushing water, according to AP. President Macky Sall cut short his trip to South Africa, and was returning to Senegal where he had ordered a full emergency response, said spokesman Abou Abel Thiam Monday. "These rains are worse in terms of their intensity. If you just look at the quantity of the water," said Thiam. "We have never seen 156 millimeters (6.1 inches) of rain fall in a two-hour window. That's what happened yesterday morning."
