KABUL, Afghanistan, Feb. 6 (UPI) -- Afghanistan's intelligence agency said four people were detained for plotting an attack in the capital city of Kabul that killed three police officers.

The National Directorate of Security said the Afghan Taliban was incapable of plotting an attack as complex as that of two weeks ago, and suspected what it called "spy agencies" were behind the incident.

Spokesman Shafiqullah Tahiri said the disruption to Kabul roads and traffic was well-coordinated, with delineated tasks for carrying out the attack.

The eight-hour episode of violence included a firefight in the streets, and killed three police officers and five militants, the Afghan news agency Khaama Press reported Wednesday.
