Washington- The US State Department has approved Pakistan’s request to purchase US-made attack helicopters, missiles and other equipment valued at almost $1 billion, aimed at fighting insurgents in the country.

US defence companies are currently involved in a three-way tussle with Russia and China to sell weapons to Pakistan.

Pakistan had requested 15 AH-1Z Viper helicopters made by the Bell arm of Textron Inc alongside 1,000 Hellfire missiles produced by Lockheed Martin Corp and a host of other communications and training equipment.
