Defying official threats and an intimidating police and paramilitary presence, protesters again took to the streets of Tehran June 20—although security forces this time prevented them from gathering in large numbers by massively occupying all public plazas and thoroughfares. Opposition leader Mir Hossein Mousavi appeared at a demonstration in south of the city and called for a general strike if he were to be arrested. "I am ready for martyrdom," he told supporters.

Ethiopian troops have reportedly crossed into Somalia after the transitional government there made a plea for foreign forces to help battle insurgents. Somalia's parliamentary speaker made the request June 20 after several days of heavy fighting in the north of the capital, Mogadishu. "The government is weakened by the rebel forces. We ask neighboring countries—including Kenya, Djibouti, Ethiopia and Yemen—to send troops to Somalia within 24 hours," Sheikh Aden Mohamed Nur AKA "Madobe." Echoing remarks made by Somali President Sheik Sharif Sheikh Ahmed in recent days, Madobe says the government is fighting al-Qaeda, which has established bases in Somalia and is determined to take over the country.

Gunmen ambushed and killed 24 Algerian paramilitary police in the country's deadliest insurgent attack in nearly a year, the local newspaper Echorouk reported June 18. The militants attacked the previous evening with roadside bombs and rifles when the police passed in a convoy along a highway about 180 kilometers east of the capital. When they left the scene of the attack they took with them six police off-road vehicles as well as weapons and police uniforms.

The UK-based advocacy group Survival International has published an eyewitness account of the killings in the Peruvian Amazon that caused shockwaves around the world.

Local residents in the Mexican village of Xico blocked roads for several days to prevent construction of a cellphone tower at the local pueblo of San Marcos. Following violent confrontations at the roadblocks between pro- and anti-antennae residents, Xico mayor Rogelio Soto Suárez called in elite anti-riot forces from the Veracruz state Auxiliary Police Institute (IPAX) to permit construction of the tower "by force." Activists say they petitioned town authorities to have the tower relocated further away from the pueblo and its schoolhouse, fearing the health impacts on their children.

A WHO study finds (unsurprisingly) that non-motorists disproportionately bear the brunt of traffic fatalities. Car accidents are the 10th leading cause of death in the world, and are on track to become the fifth leading cause by 2030. And the Washington Post (June 17) headlines the story "Fewer Cars, More Traffic Fatalities"—as if the problem were too few cars!

Last weekend, Shawna Forde, 41, leader of the Minuteman American Defense (MAD) group, and two of her associates were arrested in connection with the murder of a 9-year-old girl, Brisenia Flores, and her father, Raul, in Arivaca, Arizona. Local police are reporting that Forde and her posse broke into the Flores home dressed as law enforcement officers looking for money and drugs to finance her border-watch group—with the intention of leaving no witnesses behind.

In a new report issued after a a 10-day fact-finding trip to Colombia, a UN investigator accuses the country's military of killing hundreds of civilians over the past six years and falsely identifying the dead as guerilla fighters. Philip Alston, UN rapporteur on extrajudicial executions, said June 19 that the killings, which mostly took place since 2002, were part of a widespread systematic practice (known in Colombia as "false positives").
