Pakistani authorities have evacuated more than half a million people in Sindh province, threatened by the worst floods in 80 years. The floods have submerged several villages and killed over 1,600 people and devastated millions. The UN Office for the Coordination of Humanitarian Affair said that monsoon rains continue to fall and at least 11 districts are at risk of flooding in Sindh, where more than five lakh people have been relocated to safer places. Meteorologists said flood waters are moving at high levels in north Sindh province and would enter the town of Sukkur by Saturday.
