Roadside bombs kill 5 NATO troops

? Five NATO troops died in roadside bombs in Afghanistan, the alliance said Saturday, as international forces announced that they had foiled a terrorist attack on an upcoming conference in Kabul to be attended by leaders from more than 60 nations.

Security is being tightened across the capital for Tuesday’s conference, which is attracting the heads of NATO, the United Nations and top diplomats, including U.S. Secretary of State Hillary Rodham Clinton.

Acting on intelligence, a combined international and Afghan commando force captured a Taliban bomb-making expert Friday night in Kabul, NATO said.
