A cocaine trafficking case against Colombian rebel leader Ricardo Palmera (AKA Simón Trinidad) ended in a mistrial April 21—the second time a jury has deadlocked in a trial the US hoped would provide a symbolic victory against the FARC guerillas. A first trial ended last year with a jury deadlocked at 7-5 favoring acquittal. Palmera—who became the first FARC member to be extradited in 2004—is already serving a 60-year term on a hostage-taking charge. It is unclear whether the government will bring the drug case to trial for a third time. (AP, April 21)

On April 20 a bomb exploded outside the offices of Spain's ruling Socialist party in the Basque town of Elgoibar (Guipúzcoa province), causing considerable damage but no injuries. Police said the blast followed a telephone warning in the name of the armed separatist group ETA. (AP, April 20) While the attack made some international headlines, there was little note that it came one day before a trial opened against 27 members of Basque pro-amnesty organizations on charges that they are ETA fronts. The 27, members of Askatasuna, Gestoras Pro-Amnistía, Behatokia and Senideak, refused to respond to questioning by the Spanish prosecutor. The case stems from an eight-year inquiry by Baltasar Garzón, Spain's leading anti-terror investigator. (EiTB24, April 21)

Thousands marched in Yerevan April 24, the 93rd anniversary of the start of the mass killing campaign of at least 1.5 million Armenians by the Ottoman Empire.

Many carried flags of the 23 countries whose governments or parliaments have recognized the killings as genocide, including Canada, France, Switzerland and Poland.

Officials in Georgia are seeking to use the alleged downing of a Georgian reconnaissance drone by a Russian warplane to build international support for reducing the Kremlin's "peacekeeping" role in the separatist enclaves of Abkhazia and South Ossetia. Georgia's Foreign Ministry asserts that a Russian MIG-29 shot down the Georgian Interior Ministry drone off the Black Sea coastline of Abkhazia April 20. Georgian President Mikhail Saakashvili says the drone's final video footage provides "clear proof" of a Russian violation of Georgian airspace.

After an eight-month strike, the Grupo Mexico mining company has started to shut down its San Martin copper, silver and zinc mine in Sombrerete municipality in the central Mexican state of Zacatecas, according to Jesus Jiménez, a delegate in Zacatecas and Jalisco for the National Union of Mine and Metal Workers of the Mexican Republic (SNTMMRM). Jiménez said the company has already terminated 100 of the mine's 450 workers on a claim that the mining operation was unsustainable. The workers went on strike on July 30, 2007, as part of a strike over safety conditions that included the huge copper mine in Cananea, Sonora, and a mine in Taxco, Guerrero. Grupo Mexico has reportedly lost $120 million in revenues at San Martin since the strike began. (La Jornada, April 18)
