At least 23 inmates have been killed and scores wounded in days of rioting at the overcrowded La Mesa prison in the Mexican border city of Tijuana. Violence first broke out Sept. 14 during family visiting hours after a prisoner died inside, apparently at the hands of guards. Prisoners took advantage of the greater mobility afforded by the visiting hours to seize work implements such as picks and shovels to use as weapons, and set mattresses on fire with cigarette lighters. Four prisoners were killed in the initial outbreak; the remainder met their deaths as Baja California state police stormed the prison Sept. 18. Authorities said prisoners also used firearms, but no guards were among the casualties.

Unknown assailants lobbed grenades through the crowded town square in Morelia, Michoacán, during Independence Day celebrations Sept. 15, killing seven people and injuring more than 100. The first explosion hit just after 11 PM as bells began to ring across Mexico and Michoacán's Gov. Leonel Godoy was delivering the traditional "grito" of independence before thousands of revelers. President Felipe Calderón, whose hometown is Morelia and has mobilized thousands of soldiers to Michoacán to fight drug gangs, delivered a nationwide address the next day calling on Mexicans to unite against the cartels. "On this national holiday, there are cowards hidden in the crowds of patriotic people that have converted joy into sadness and the happiness of Mexican families into sorrow," he said.

Leahy, 26, all formerly assigned to the 1st Batallion, 18th Infantry Regiment, are also charged with conspiracy to commit premeditated murder and obstruction of justice.

Presumed al-Qaeda militants attacked the US Embassy in the Yemeni capital Sana Sept. 17, exploding a car bomb and firing automatic weapons and rocket-propelled grenades in an assault that left 16 dead—six militants, six guards and four civilians. Three police officers and seven civilians were injured, including children in a residential compound across the street from the embassy. It was the deadliest attack on a compound that has been targeted four times in recent years by bombings, mortars and shootings. With the attackers—some dressed in army uniforms—unable to penetrate the compound's massive security barriers, civilians waiting in line for visas outside the embassy were among the casualties. Susan Elbaneh, 18, a US citizen from Lackawanna, NY, recently wed in Yemen in an arranged marriage, was killed along with her husband. (AP, Sept. 17; The Scotsman, Sept. 18)
