Mexico's northeastern border state of Tamaulipas—just across from Texas' Gulf Coast—has for years been engulfed in an under-reported war, as the Gulf Cartel and its rogue offspring the Zetas battle for dominance over the narco-trafficking "plaza" (zone of control). The current flare-up in the border town of Reynosa may signal a turning point. Street gun-battles have become so common in the town that authorities have instituted a color-coded alert system to warn citizens. The town has been on "red alert" repeatedly over the past days, and there are signs that the long struggle is entering an endgame.

Javier Duarte, the fugitive ex-governor of Mexico's Veracruz state, was detained in Guatemala on April 15 in a joint operation by Interpol and Guatemalan police. He's now awaiting extradition back to Mexico, where he is wanted on charges of money laundering and protecting organized crime. Duarte was governor of Veracruz from 2010 until he stepped down last October, shortly before the end of his term. He was doing so in order to face the allegations against him—but then he disappeared and went on the lam.

After President Donald Trump's inauguration, Mexico saw a wave of angry protests against his proposed border wall, with more than 20,000 marching in Mexico City on Feb. 12, chanting "Pay for your own wall!" But now this wave of anger is crystalizing around concrete legal initiatives that could be very problematic for the White House. First, the front-runner for next year's Mexican presidential election, the left-populist Andres Manuel López Obrador, has filed a complaint with the Inter-American Commission on Human Rights against the proposed wall.

Edgar Veytia, attorney general of Mexico's western state of Nayarit, was once himself targeted for death by the narco-gangs. But on April 8 he was ordered jailed by a US federal judge in Brooklyn, facing charges of trafficking cocaine, heroin and methamphetamine into the United States. Veytia, who has now won the epithet in Nayarit of "Diablo," allegedly netted at least $250 million in protection payments from a smuggling ring since his election in 2013, according to the Daily News. After entering a "not guilty" plea, Veytia was remanded to the Metropolitan Detention Center in Brooklyn pending a bail hearing.

More than 250 human skulls were unearthed from a mass grave outside Mexico's port city of Veracruz, state prosecutor Jorge Winckler announced March 14. Winckler said the remains are of cartel victims, slain some years earlier. While details on how this latest find came to light were not forthcoming, the survivors' group Colectivo Solecito has been carrying out its own search for "narco-graves" in Veracruz state, hoping to discover the remains of disappeared loved ones. Last year, the collective discovered some 30 clandestine graves, but this would be the biggest such gruesome discovery yet.

Amid rapidly deteriorating relations between the US and Mexico, reports are emerging that President Donald Trump openly threatened military intervention in a phone call with his counterpart Enrique Peña Nieto. According to a partial transcript of the conversation obtained by the Associated Press, Trump told Peña Nieto: "You have a bunch of bad hombres down there. You aren't doing enough to stop them. I think your military is scared. Our military isn't, so I just might send them down to take care of it." ("Bad hombres" is a term Trump also used in his final debate during the presidential campaign to refer to Mexican narco-gangs.)

The planned meeting in Washington between President Trump and his Mexican counterpart, Enrique Peña Nieto, was called off after Trump signed his Jan. 25 executive order decreeing construction of a wall on the border—accompanied with more bluster about how Mexico will pay for it. Since the cancelation, Trump and Peña Nieto have engaged in an unseemly Twitter war, each taking responsibility for calling off the meeting. Things got worse when the White House raised the option of making Mexico pay for the wall with a 20% tariff on all goods coming in from our southern neighbor. The threat portends a trade war with the United States' third biggest trading partner.

Isidro Baldenegro López, a Tarahumara indigenous activist in northern Mexico's Chihuahua state who fought for the preservation of forest lands, was assassinated last week, in an attack near the home of a family member in the pueblo of Coloradas de la Virgen, Guadalupe y Calvo municipality. Although the Chihuahua state prosecutor has not officially registered a homicide, Baldenegro's relatives confirmed that he had been slain and buried in the village. The assailants have not been identified, but his relatives say they believe the gunmen were part of the same network that has threatened and slain other local residents for defending the pueblo's forest lands and opposing illegal timber felling.
