Officials said all the frontline IAF bases along India’s western border have been kept on maximum alert. Tensions between the two countries escalated after Indian fighters bombed terror group Jaish-e-Mohammed’s biggest training camp near Balakot deep inside Pakistan on February 26. Pakistan retaliated by attempting to target Indian military installations on February 27. However, the IAF thwarted their plans. The Indian strike on the JeM camp came 12 days after the terror outfit claimed responsibility for a suicide attack on a CRPF convoy in Kashmir, killing 40 soldiers.
