Governor Rick Perry says state and federal authorities are trying to get answers regarding a Mexican military helicopter that crossed the Texas-Mexico border late Wednesday afternoon.
U.S. Customs and Border Protection had confirmed that a Mexican military helicopter crossed the border near Falcon Dam in Zapata County before returning to Mexico without landing.
Calls for comment to the Mexican Navy were not returned. The Mexican army and navy are both involved in anti-drug trafficking operations in Mexican border cities.
In a prepared statement Friday, Perry called for better communication between U.S. and Mexican authorities along the border.
