The US Senate has voted a controversial law endorsing President George Bush's proposals to interrogate and prosecute foreign terror suspects. The 65-34 vote followed Thursday's backing by the House of Representatives for almost identical legislation. The new bill could be signed into law by the president within a few days, BBC reported. Under the new legislation, special tribunals will be set up to question and try several hundred suspects being held at Guantanamo Bay, Cuba. Human rights activists have expressed concern that the new tribunals might not give the same protection to suspects as the existing civil courts.
