WASHINGTON, Muharram 16, 1432, Dec 22, 2010, SPA - The Senate is poised to approve a nuclear arms pact with Russia, handing President Barack Obama a huge victory on his top foreign policy priority. Passage of the New START treaty appeared assured after 11 Republicans joined Democrats in a vote Tuesday to end debate on the pact. That signaled that Obama should have the two-thirds majority he needs when the Senate votes on final approval later today, the Associated Press reported. --SPA 11:13 LOCAL TIME 08:13 GMT www.spa.gov.sa/848248
