Kabul attacks show intelligence failure: Karzai

President Hamid Karzai has said that coordinated attacks by Taliban insurgents across Afghanistan showed an intelligence failure on the part of both Afghan and NATO forces.The terrorists infiltration in Kabul and other provinces is an intelligence failure for us and especially for NATO and should be seriously investigated, Karzai said in a statement.On the other hand, a militant arrested in the attacks on the Afghan capital and three other cities has confessed that the 18-hour assault was carried out by the Haqqani network, a lethal group of fighters with ties to the Taliban and al-Qaida, a top Afghan security official said Monday.Thirty-six insurgents were killed during the brazen attacks that also claimed the lives of eight policemen and three civilians and proved that militants can still penetrate Afghan security after 10 years of war, said Interior Minister Besmillah Mohammadi.The violence showed the Taliban and their allies are far from beaten and underscored the security challenge facing government forces as U.S. and NATO troops draw down. The majority of international combat troops are scheduled to leave by the end of 2014.It was the most widespread attack in the Afghan capital since an assault on the U.S. Embassy and NATO headquarters last September — an assault also blamed on the Haqqani network, which commands the loyalties of an estimated 10,000 fighters considered one of the most serious threats to NATO in Afghanistan.
