Mexico urges respect for treaties after Texas seizes nine islands on Rio Grande

Texas has taken control of nine islands on the Rio Grande, citing border security needs, while Mexico insists ownership is determined by the International Boundary and Water Commission. The Texas General Land Office claims the islands were previously unclaimed, but Mexico's Foreign Ministry emphasizes that the 1970 Boundary Treaty governs ownership and requires joint approval for any actions on these territories. Experts argue that the determination of ownership is not a state matter and should be resolved by the IBWC, which assesses changes in the river's channel. The situation raises questions about the legitimacy of Texas's claims and the implications for border security operations.
