(Reuters) – Authorities in Eagle Pass, Texas, have closed one of the city’s two border crossings to Mexico due to “safety concerns,” the Customs and Border Protection agency said on Wednesday.

The agency said local authorities closed Bridge II linking the city to Piedras Negras, Mexico, to traffic in the morning citing safety concerns, which local news media said were prompted by the discovery of a “suspicious device.”

Eagle Pass is not one of the principal hubs for trade or visitors over the 2,000-mile (3,200-km) U.S. Mexico border.

True. That hub is mainly Hidalgo County, about which we’ve reported before. Things are not as tranquil as reported there. We’ll have more to report from that county before long.

It’s not widely known outside the Rio Grande Valley, but a “suspicious device” was discovered in Starr County, Texas back in August. It was an improvised explosive device. It was discovered on a ranch through which illegal aliens often slip into the United States.

If illegal aliens and coyotes can slip through there, so can the type of people who tend to play around with IEDs.

There’s no word yet on the nature of today’s suspicious device in Eagle Pass.
