Police officers guard the entrance to the Fundacion Santa Fe clinic, in Bogota, where Colombian presidential candidate Miguel Uribe is hospitalized after being shot. Thirty-nine-year-old Senator Miguel Uribe has successfully undergone initial surgery, according to authorities. He was speaking to supporters in the capital when a gunman shot him twice in the head and once in the knee before being detained. A security guard managed to detain the suspected attacker, a minor who is believed to be 15 years old. Uribe was airlifted to hospital in "critical condition" and underwent a "neurosurgical" and "peripheral vascular procedure," the Santa Fe Clinic in Bogota confirmed. IMAGES
