The US dropped its most powerful non-nuclear weapon, the GBU-43/B Massive Ordnance Air Blast Bomb, on an area of eastern Afghanistan said to be controlled by ISIS militants. The April 13 air-strike targeted a cave complex believed to be used by fighters affiliated with the Islamic State's self-decalred "Khorasan Province" in Achin district of Nangarhar, near the border with Pakistan. A US special forces solider was killed in the same area last week. The MOAB, nicknamed the "mother of all bombs," is a 21,600-pound, GPS-guided munition that is the largest among the Pentagon's series of so-called "bunker-busters." The strike marked the first time it has been used in combat. (The Independent, CNN, LWJ)

Egyptian authorities have declared a three-month state of emergency after twin ISIS bombings killed 43 at two Coptic churches in the Nile Delta cities of in Tanta and Alexandria on Palm Sunday.

At least three guards were killed when riot police were sent in to storm the Etapa 2 juvenile detention center outside Guatemala City, where members of the notorious Barrio 18 narco-gang had seized cell-blocks and taken hostages March 20. Riot troops were ordered to take the facility despite desperate pleas from guards being held hostage. Latin American Herald Tribune reports that before the bloody climax, hostages had shouted from windows, urging authorities to negotiate with their captors. "We are begging and the government doesn't want to do anything," one reportedly cried. "They give no attention to our lives."

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.

Most of President Barack Obama's actions to forestall climate change were wiped out March 28 as President Donald Trump revoked or revised limits on carbon emissions from power plants and opened federal lands to coal mining. Trump's executive order applies to Obama's Clean Power Plan, and an October 2015 rule entitled "Carbon Pollution Emission Guidelines for Existing Stationary Sources: Electric Utility Generating Units." Even federal planning for the planet's warming climate will no longer be allowed, as Trump revoked Obama's executive order of 2013 requiring federal agencies "to integrate considerations of the challenges posed by climate change effects into their programs, policies, rules and operations to ensure they continue to be effective, even as the climate changes."

Bolivia's President Evo Morales signed into a law March 8 a bill passed by the country's congress that nearly doubles the area of national territory open to coca leaf cultivation. Law 906, or the General Law of Coca Leaf, envisions new legal commerical and industrial uses for the leaf. It replaces the far more restrictive Law 1008, passed during the Reagan-led drug war militarization of the Andes in 1988—when Bolivia's democratic transition after years of military rule was still new. "The hour has arrived to bury Law 1008, which sought to bury coca leaf in Bolivia," the presidency said in a statement. "This is an historic day." The signing ceremony at the presidential palace was witnessesed by a delegation of coca-growers.
