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.

Texans are reeling from the major flood disaster over the holiday weekend that killed at least 108 people, with the majority of the deaths taking place in Kerr County. At least 23 people remain missing.
