WASHINGTON (AP) - The Latest on migrants missing after their raft flipped on the Rio Grande (all times local):

4:35 p.m.

A law enforcement official says a 10-month-old baby has been found dead after a raft carrying the child and eight others flipped on the Rio Grande as they tried to cross the U.S.-Mexico border.

A 7-year-old boy and another child and man are still missing.

The number of migrant families crossing the U.S.-Mexico border has skyrocketed, and they sometimes try to traverse the river. The group made the attempt Wednesday evening near Del Rio, Texas when the raft overturned.

The law enforcement official had direct knowledge of the incident but was not authorized to speak publicly and spoke to The Associated Press on condition of anonymity.

Border agents encountered the father of the boy and rescued his wife and 6-year-old son. A second man and his 13-year-old son were rescued nearby.
