Mexico has come to the aid of the United States following Hurricane Harvey, sending Red Cross volunteers, food and supplies to a country whose president has proposed building a wall to keep the two neighbors apart.

Mexican volunteers wearing white vests labeled "Cruz Roja Mexicana" are distributing food and lending a sympathetic ear to some of the 1,800 storm refugees at the George R. Brown Convention Center, a temporary shelter.

A caravan of Mexican storm relief was due to be shipped north for victims of a storm that has killed some 60 people and left tens of thousands homeless since first coming ashore Aug. 25.
