Afghan security forces have foiled a plan by insurgents to attack a major international hotel in Kabul, officials said on Tuesday. Describing the plan as "major and aggressive", a spokesman for Afghanistan's National Directorate of Security (NDS) said the attack could have caused carnage, although he refused to give details. "Terrorists planned to launch an attack on a five-star hotel. We avoided the assassination of scores of our people and the destruction of an important installation," said Shafiqullah Tahiri, the deputy spokesman for the NDS. Investigations into the attack were continuing, he was quoted as saying by Reuters.
