Bombings kill 18; offensive launched

BAGHDAD, Iraq - A string of four apparently coordinated bombings in seven minutes Tuesday killed 18 people in northern Iraq, ending a relative lull in violence, and a television station aired a video showing gunmen threatening to kill a Turkish hostage.

Hundreds of U.S. and Iraqi soldiers descended on the remote northern city of Tal Afar near the Syrian border, launching a major operation against insurgents, military officials said.

A Sunni politician, meanwhile, claimed two insurgent groups were ready to open talks with the government and eventually join the political process.

Blair seeks Bush's support in Africa, global warming

WASHINGTON - A U.S. commitment to providing $674 million for famine relief in Africa may take some of the sting out of President Bush's opposition to a proposal by British Prime Minister Tony Blair to spend even more money.

However, the other issue topping Blair foreign policy this year - fighting global warming - may further strain his relationship with Bush. Blair has made the issues the twin focus of Britain's yearlong chairmanship of the G-8 group of wealthy nations, yet Bush has rejected many of his close ally's ideas on Africa and the environment.

Bush welcomed Blair to Washington on Tuesday, their first meeting since Blair won a third term in office and his Labour Party suffered heavy losses in Parliament, largely because of unhappiness about his support for the Iraq war.

No injuries were immediately reported.

give us a time,'' said State Department spokesman Sean

McCormack.

Academies call for greenhouse gas cuts

LONDON - The U.S. National Academy of Sciences joined similar groups from other nations Tuesday in a call for prompt action to reduce greenhouse gas emissions, warning that delays will be costly.

The statement was released as British Prime Minister Tony Blair was meeting with President Bush in Washington.

Blair has made action on climate change a priority for the July G-8 summit. Bush opposes the Kyoto Protocol on global warming, and his administration questions scientists' views that man-made pollutants are causing temperatures to rise.

civilian bus in an attack that killed 38 people and injured 71, saying they were targeting government security forces.

Serb paramilitary unit was part of Milosevic's police

BELGRADE, Serbia-Montenegro - Former Yugoslav President Slobodan Milosevic's police directly controlled a notorious Serb armed unit known as the Scorpions and gave them a license to kill in Bosnia and Kosovo, a police document showed Tuesday.

The unit was one of the several Serbian paramilitary contingents that spread fear and conducted massive ethnic cleansing operations against non-Serbs during the Balkans wars in the 1990s, prominent military analyst Dejan Anastasijevic said.
