Sharjah fire crews tackled a blaze in a high-rise building that sent smoke pluming across the city's waterfront. The fire was reported at 6.55am on Thursday in the upper floors of the unnamed tower, which was under construction. Workers were led to safety and no injuries were reported. Photos of the building, close to Sharjah Expo, showed smoke rising across the area. Sharjah Civil Defence said the fire started in the upper floors and spread through the tower, which is about 45-storeys tall. It was quickly brought under control and crews remained at the scene on Thursday afternoon. Images appeared to show extensive smoke damage to the upper part of the high rise, one of the tallest in the area.
