WASHINGTON (AFP) - US Secretary of State Hillary Clinton slammed the capture of a US soldier by Taliban forces in Afghanistan as outrageous and vowed to do everything we can to free him, in an interview aired Monday. We are attempting to do everything we can to locate him and free him, Hillary told US television network ABC in New Delhi during a visit to India. The Taliban, whose resurgence in Afghanistan has led to heightened unrest in the country, released a video over the weekend of a visibly-shaken captive US soldier who was snatched by the militants in Afghanistan late last month. The US military is still trying to locate and bring him back, said Bryan Whitman, a Pentagon spokesman, of 23-year-old Private First Class Bowe R Bergdahl. In the 28-minute clip posted online, the soldier identified by the Pentagon on Sunday as Bergdahl sits on the floor in traditional pale grey Afghan clothing and pleads for US troops to leave the war-torn nation. The shaven-headed young man, who sports a fledgling beard and appears nervous and frightened, answers questions in English, occasionally choking back sobs as he tells his captors he is scared and wants to see his family. I mean its just outrageous. Its a real sign of desperation and inappropriate criminal behaviour on the parts of these terrorist groups, Hillary said. So we are going to do everything we can to get him. A US military spokesman in Kabul had earlier confirmed that the man in the video was the same soldier who went missing from his base in southeastern Paktika province on June 30, and condemned the video as propaganda. Hundreds of US soldiers and troops from other nations have been killed in Afghanistan battling the widening Taliban-led insurgency. But the abduction late last month is believed to be the first time militants have snatched an American soldier in Afghanistan since the war began in 2001. Meanwhile, Hillary Clinton said in an interview aired Monday that North Koreas nuclear and missile threats are signs the reclusive regime is craving world attention and acting out like unruly teenagers. We werent going to give the North Koreans the satisfaction they were looking for which is to try to elevate them again to centre stage, Hillary told US television network ABC. What weve seen is this constant demand for attention, and maybe its the mother in me or the experience that Ive had with small children and unruly teenagers and people who are demanding attention. Dont give it to them, she insisted. They dont deserve it. They are acting out in a way to send a message that is not a message were interested in receiving. She also downplayed the potential threat from North Koreas quiver of missiles, one of which Washington says was tested April 5. Theyre no real threat to us, Hillary said. We know that our allies Japan and South Korea are very concerned, but we share information. They watch what we watch and understand whats really going on there. Hillary also downplayed the threat that North Korea poses to the United States, saying: They dont pose a threat to us. We know that our allies, Japan and South Korea, are very concerned. She said her comment earlier this month that everyone is very sorry about an incident that resulted in North Korea detaining two US journalists was a recognition of what the two women themselves have said. Our most important goal now is to make sure that these young women get home safely and get returned to their families, Clinton said. Laura Ling and Euna Lee of the US media group Current TV were arrested in March near the China-North Korea border, convicted of great crimes, and sentenced to 12 years hard labour. The comments came as the United States and its negotiating partners were preparing a comprehensive package of incentives to encourage North Korea to scrap its nuclear weapons, a senior US envoy said Monday. Kurt Campbell, assistant secretary of state for East Asia and Pacific affairs, did not elaborate on the package, which is still being finalised. But he said it would require Pyongyang to take irreversible steps towards denuclearisation in return. Yonhap news agency said he made his comments at a breakfast meeting with senior South Korean journalists. A US embassy spokesman confirmed the main points of the Yonhap report. Six-nation nuclear disarmament talks grouping the two Koreas, China, Japan, the US and Russia began almost six years ago but bogged down last December. After the United Nations Security Council censured its April 5 long-range rocket launch, the North announced it was quitting the talks and restarting its atomic weapons programme.
