Five Yemeni soldiers were killed in in a suspected ambush by "al-Qaeda in the Arabian Peninsula" while on patrol in the Shabwa province in southern Yemen July 21. A day earlier, dozens of pro-government tribesmen were killed in clashes with Shi'ite Houthi rebels in northern Saada province, including tribal leader Sheikh Zaidan al-Maknaiee, his son and four bodyguards.

Nicaragua's President Daniel Ortega on July 20 accused Colombia of granting exploration permits to oil companies on Nicaraguan territory. Ortega was referring to disputed waters along the Caribbean maritime border between the two countries. The Colombian government sold permits to 80 foreign companies for 230 sites across the country last month—including in the disputed waters. A case over the dispute is still pending at the International Court of Justice (ICJ).

Some 5,000 indigenous campesinos from across Colombia marched in downtown Bogotá July 21 to protest a pact that gives US forces greater access to Colombian military bases. The "Patriotic March" on Plaza Bolívar came the same day as 30,000-strong celebrations in the capital city's central square marking the nation's bicentennial. President Alvaro Uribe presided over the official rally. The campesinos marched on the plaza from the National University campus, which has served as a staging ground for the protest, and where classes are suspended.

Police in Yulin, Shaanxi province, detained eight people following a July 17 clash at a coal mine that left dozens injured. The eight suspects include both residents of nearby Fanjiahe village, Hengshan county, and workers at the Shandong Coal Mine. The clash involved nearly 200 and left 87 injured, authorities said. It began when more than 100 villagers, armed with shovels and other tools, entered the mining site and smashed equipment in a bid to stop production.

In what is possibly the worst oil spill in China's history, some 430 square kilometers of the Yellow Sea are covered with a slick following a July 16 explosion at a pipeline terminal in the northeast port of Dalian. At least one worker has drowned in crude during the clean-up operation. The slick has doubled in size despite earlier government assurances that it was being contained. Supplies have been cut to two local PetroChina refineries. The terminal receives crude from Yellow Sea rigs run by the China National Offshore Oil Corp. (CNOOC). The Chinese government estimates the spill at 400,000 gallons. A Beijing-based biotechnology company, Weiyeyuan, is providing 23 tons of oil-eating bacteria to help clean up the slick.

On July 21, Rep. Eliot Engel (D-NY), chair of the House Foreign Affairs Subcommittee on the Western Hemisphere, released a report he commissioned from the Government Accountability Office (GAO) on the Merida Initiative. Western Hemisphere Subcommittee ranking member Connie Mack (R-FL) joined Engel's request for the report, which argues that current evaluation mechanisms for the Merida Initiative need improvement. The report also finds that Merida funding funding has been mired in bureaucratic hurdles, but is now moving to Mexico and Central America at a much more rapid pace.

Colombia asked the Organization of American States July 16 to convene a meeting of its permanent council to address Bogotá's accusation that guerillas are operating out of Venezuelan territory.

Nearly 400 have been killed in recent clashes between the Sudanese army and Darfur's main rebel group, according to Sudanese state media. Most of the casualties were members of the Justice and Equality Movement (JEM). UN peacekeepers in Darfur confirmed that there were at least two major clashes between the two sides. Gen. Al-Tayeb al-Musbah, of the Sudanese army, told the state-run Suna news agency that the army destroyed "scores of JEM vehicles" during the fighting.
