"Mexican authorities seize Soviet-era missile in Playa Bagdad."

Here is an excerpt from this article on ValleyCentral.com:

"Mexican authorities are investigating the discovery of a Soviet-era anti-aircraft missile south of where the Rio Grande empties into the Gulf Of Mexico. The El Universal newspaper reported that a hotel employee from the beach resort community of Playa Bagdad made the discovery on Thursday night. The newspaper reported that the discovery prompted the mobilization of the Mexican navy, soldiers and police. Authorities seized the missile and searched the area for other explosives but did not find any. El Universal reported that the type of missile seized is fired from a shoulder launcher and has a range of a little over two miles. The newspaper reported that the seized weapon  is a first-generation Soviet military heat-seeking missile."

Analysis: It's still too early for me to be able to do more than speculate on the origins of this missile, but I'll do just that. The Spanish El Universal article has a few more specifics on the missile capabilities, and I wish the Mexican authorities would have just come out and said the make and model. From what very little I can gather (and again, the better info is in El Universal, if you read Spanish), there's a chance the missile might be an old Soviet SA-7:

"In 1972 the Soviet Union introduced what is known as the SA-7.  It is what is now known as a'1st generation' MANPAD (man portable air defense).  It is a shoulder launched passive IR  seeking missile.  It is passive meaning that it emits nothing that can be detected (such as a laser or radar signal).  It’s basic operation is based on the seeker head.  The head is an uncooled seeker that can detect heat signatures in the medium Infra-Red bands of the electromagnetic spectrum.  This basically corresponds with the energy emitted from the exhaust of an engine."

As for what an SA-7 was doing on a Mexican beach (if, in fact, that's what it was), that's anyone's guess. Maybe it fell off a gun-running boat and washed ashore. Maybe an arms shipment was brought to shore there for a DTO and that one got left behind. Maybe it made the trip from Cuba to Mexico because it was unhappy with the Castro brothers and communist rule. Bottom line, there are currently no images available of the missile, and only two news stories that I can find on the incident...not exactly independent confirmation from multiple credible sources. If more information becomes available, I'll post an update.
