At 2.09 am on Saturday, Ahmad Subhan, who lives near an air base in the Pakistan military garrison city of Rawalpindi, heard the first explosion that rattled the windows of his house - and took South Asia to the brink of war.

India scaled down its diplomatic relations with Pakistan as part of its retaliatory measures. It expelled all Pakistani defence attachés, declaring them "persona non grata" (unwelcome) and announced it would withdraw its own defence advisers from its high commission in Islamabad.

India also has a long-standing policy of refusing to allow foreign mediation when it comes to the status of Muslim-majority Kashmir - a disputed region claimed by both India and Pakistan in its entirety - which has been at the center of the latest conflict with Pakistan and which India regards as a strictly internal matter.
