Expressing serious concern over the recent attack on a Pakistani naval base, senior BJP leader L.K. Advani on Thursday said India should take serious note of the incident which raises questions whether terrorist elements were trying to make the neighbouring country a 'jihadi state'.

Fifteen hours after brazenly storming into Pakistan Navy's key Mehran airbase in the heart of the port city of Karachi, heavily-armed Taliban militants were still holding onto parts of the base after destroying two US-made surveillance aircraft and killing 13 security personnel.
