Mexico calls on US for 'full inquiry' into use of non-lethal weapons at border

Mexico's foreign ministry presented a diplomatic note to the U.S. government on Monday calling for "a full investigation" into what it described as non-lethal weapons directed toward Mexican territory on Sunday, a statement from the ministry said.

U.S. authorities shot tear gas canisters toward migrants in Mexico on Sunday near the border crossing separating the Mexican city of Tijuana from San Diego, California, after some of them attempted to cross into the United States.
