Pakistan Prime Minister Imran Khan has asked India for a dialogue as hostilities between the two nations spiked this morning following an engagement between the air forces. Pakistan and Indian Air Forces had not engaged since the 1971 war. The surge in hostilities - the worst in decades -- has come within a fortnight of the Jaish-e Mohammed suicide attack on a CRPF convoy in Jammu and Kashmir's Pulwama, in which 40 soldiers lost their lives.
