Read the following passage carefully and answer the questions that follow. I rise to apprise this august House of the foreign policy dimension of our response to the Pahalgam terrorist attack, going into the preparations for Operation Sindoor and how foreign policy was handled during Operation Sindoor. As all the honourable members would appreciate, it was important to send a clear, strong and resolute message after the Pahalgam attack. Our red lines had been crossed and we had to make it very apparent that there would be serious consequences. As a result, the first step which was taken was that a meeting of the Cabinet Committee of Security took place on the 23rd of April, and that meeting decided that:

• One, the Indus Water Treaty of 1960 will be held in abeyance with immediate effect until Pakistan credibly and irrevocably abjures its support for cross-border terrorism.
• Two, the integrated checkpost Attari would be closed with immediate effect.
• Three, Pakistani nationals who were traveling under SAARC visa exemption scheme would no longer be allowed to do that.
• Four, the Defence, Naval and Air Advisors of the Pakistani High Commission would be declared persona non-grata and,
• Five, the overall strength of the High Commission would be brought down to 30 from the number of 55. (207 words)
