The United Kingdom’s Maritime Trade Operations said the fire struck the vessel northwest of Sharjah, an Emirati sheikhdom. Emirati officials said they were working to put out the blaze some 21 miles (34 kilometers) off the coast of Sharjah. The blaze comes amid heightened tensions in the region after the U.S. killed Iranian Revolutionary Guard Gen. Qassem Soleimani in a drone strike in Baghdad and Iran fired ballistic missiles at Iraqi bases housing U.S. troops.
