DAR ES SALAAM, Dec 3 (Reuters) - At least 20 people have been killed by floods after heavy rain in the Manyara region of northern Tanzania, the ministry of health said on Sunday. Severe flooding caused by the El Nino weather phenomenon has killed hundreds of people in Kenya and Somalia in recent weeks. "We are very shocked by this event," President Samia Suluhu Hassan said in a video message posted online by the Tanzanian ministry of health. The more than 20 people were killed in Katesh village in the Hanang district of Manyara, the president said. The heavy rain on Saturday night caused landslides in some areas of Mount Hanang, domestic media outlets reported, adding that the waters also swept away livestock.
