BOGOTA, Shawwal 11, 1435, Aug 7, 2014, SPA -- Colombia's President Juan Manuel Santos will be sworn in for his second term on Thursday to face the formidable task of clinching peace with Marxist FARC rebels as a hostile opposition seeks to hobble any accord that passes through Congress, Reuters reported. Santos won re-election in June with the aid of leftist parties that back negotiations to end 50 years of war. In an unusual display of solidarity, they joined forces with the center-right Santos to block former President Alvaro Uribe's right-wing candidate, who had sought to scrap talks. Although Santos wants his second mandate to move the nation toward a post-conflict era, it will likely be a bitter four years. -- SPA 21:33 LOCAL TIME 18:33 GMT www.spa.gov.sa/1260843
