From AFP:

Pakistan hit out at India on Tuesday, branding its first nuclear-powered submarine “detrimental” to regional peace and vowing to take “appropriate steps” to maintain a “strategic balance”.

Relations between nuclear-armed rivals India and Pakistan have plummeted since Islamist gunmen killed 166 people in Mumbai last November, attacks that New Delhi blamed on banned Pakistani group Lashkar-e-Taiba (LeT).

“Continued induction of new lethal weapon systems by India is detrimental to regional peace and stability,” the foreign ministry said.
