A home-made bomb ripped through a bus terminal in Mindanao's Cotabato City May 18, killing three and injuring 15 others. About half of the casualties were children. Authorities said the motive was probably extortion, as the bus company had been receiving letters from armed groups demanding money. But Mindanao has been hit by seven bombings this year, many of them blamed on Muslim extremists linked to the Jemaah Islamiah or al-Qaeda terror networks. The bombing came barely a week after Australia and the United States warned their citizens of possible terror attacks in Central Mindanao. On May 8, a device went off in a crowded market in Tacurong, killing eight. (Manila Times, May 19; GMA, May 18)

An Israeli airstrike targeting a minivan supposedly carrying a Hamas fighter in northern Gaza City killed three people and wounded 12 on May 18. Israeli tanks also fired five shells near a housing project in the northern Gaza town of Jebaliya, wounding five. (AP, May 19) On May 17, Israel moved tanks and troops over the Gaza border and launched eight airstrikes, killing at least seven Palestinians. Some 14 rockets fired by Hamas militants in Gaza May 17 landed in Israel, six near the border town of Sderot. The government bused some Sderot residents to hotels, calling it a "respite," not an evacuation. (NYT, May 18)

Mexico May 15 called upon the US to prevent weapons from landing in the hands of drug gangs that increasingly use them to kill soldiers and police. "The firepower we are seeing here has to do with a lack of control on that side of the border," Assistant Secretary of Public Safety Patricio Patiño told the Associated Press. Patiño said that earlier that day, federal agents arrested two gunmen carrying assault rifles and half a dozen hand grenades in the city of Morelia, Michoacán—apparently on their way to carry out a hit. The escalating attacks on security forces come in response to a "radical change" in Mexico's law enforcement strategy, Patiño said, noting that Mexico is now going after the cartels' entire structures rather than just leaders.

Fidelity Investments of Boston is denying that a sharp reduction in holdings of oil companies doing business in Sudan is a result of activist pressure over Darfur. Anne Crowley, a spokeswoman for the mutual-fund giant, said the sales were decided by the managers of individual Fidelity funds. "Fidelity doesn't tell fund managers how or when to buy or sell any given stock," she said. Fidelity documents filed with the Securities and Exchange Commission this week show its ownership of PetroChina Co. shares traded on the New York Stock Exchange declined from about 4.5 million earlier this year to 420,916 as of the end of March—a decrease of more than 90%.

Javier Gómez Bermúdez, the presiding justice, warned the men that if they continued the strike they could be expelled from court proceedings and force-fed. "The trial will continue in their absence," he said. (The Guardian, May 17)
