Mexico has sent water rescue teams and firefighters to help in Texas after the holiday weekend floods that have killed at least 100 people, with many more still missing.

As the hours go by, the work does not let up for the hundreds who are searching around the clock for the victims still missing from the Central Texas floods, including an international group of first responders that came from Mexico to lend a helping hand.

The Mexican city of Acuña — which is across the Rio Grande from Texas and more than 140 miles from the most devastated flooding areas — said in a social media post on Tuesday that it has sent a rescue team from its civil protection and firefighting units to Kerr County, Texas, to assist teams from the U.S. with search and rescue efforts.
