Pakistan has said India's supersonic interceptor missile test will disturb the balance of power in the region and it plans to raise the issue at the international level. "Pakistan will raise its voice at the international level against these developments," Adviser to Pakistan Prime Minister on Foreign Affairs Sartaj Aziz said. He said Indian supersonic interceptor missile test will disturb the balance of power in the region, Radio Pakistan reported. Aziz said Pakistan is not oblivious to its defence and will continue to upgrade its defensive capabilities. He said Pakistan will definitely acquire advanced technology to improve its defence. He said India is getting cooperation from the US, which thinks a strong India is vital to contain China. Aziz's remarks came a day after India successfully test-fired indigenously developed supersonic interceptor missile, capable of destroying any incoming ballistic missile, from a test range off Odisha coast.
