ASWAN (Updated) - Egypt's ministries of health, the environment and irrigation Saturday stepped up their efforts to contain the gasoline leaked from a barger into the Nile earlier in the day. The barge has leaked some 110 tonnes of gasoline into the Nile River in southern Egypt after it became partially submerged while workers unloaded its cargo. The vessel docked Saturday in Aswan, about 700 miles (1,100 kilometres) south of Cairo, when part of the barge sank below the surface and began spewing gasoline into the river. The leak has since been stopped. Weeds contaminated by the leak have been removed as the driver of the barge has been arrested for questioning over the incident. Officials in three southern Egyptian provinces have declared a state of emergency to contain the spill and to prevent it from spreading down river. The barge belongs to the Nile Company for River Transport. Officials say it was carrying 240 tonnes of gasoline. The chief of the Luxor drinking water company urged people to stockpile water in case the spill reaches the city's water purification facilities.
