Army will decide how and when to attack: PM Modi

After attack, India revoked Pakistan's 'Most Favored Nation' status
On Friday, PM Modi chaired a CCS meeting which was called to take stock of the situation. The meeting was attended by NSA Ajit Doval and Union Ministers like Nirmala Sitharaman, Arun Jaitley, Rajnath Singh, and Sushma Swaraj.

Announcing the decision, Jaitley tweeted, "Basic customs duty on all goods exported from Pakistan to India has been raised to 200% with immediate effect."
