The Panama Canal will expand restrictions on the largest ships crossing the waterway, one of the world's busiest trade passages, the canal authority's administrator said on Wednesday, citing shallower waters due to drought. The measure follows a series of depth restrictions in the 50-mile (80 km) canal since the beginning of the year due to a drought, which authorities had hoped would ease by the start of the Central American country's rainy season.
