Foreign Secretary Vikram Misri told a parliamentary committee on Monday that the conflict between India and Pakistan was always in the conventional domain, and there was no nuclear signalling by the neighbouring country, sources said.
The sources said Misri reiterated the government's stand that the decision to stop military actions was taken at a bilateral level, as some opposition members questioned US President Donald Trump's repeated assertions about his administration's role in stopping the conflict.
Some MPs, the sources said, asked if Pakistan used Chinese platforms in the conflict.
Misri said it did not matter as India hammered Pakistani air bases.
The meeting of Parliament's Standing Committee on External Affairs, chaired by Congress MP Shashi Tharoor, was attended by a number of lawmakers, including the TMC's Abhishek Banerjee, the Congress' Rajeev Shukla and Deepender Hooda, AIMIM chief Asaduddin Owaisi, and the BJP's Aparajita Sarangi and Arun Govil.
The meeting comes against the backdrop of the Indian Armed Forces carrying out Operation Sindoor to avenge the Pahalgam attack and the subsequent military actions between the two countries.
India and Pakistan reached an understanding on halting all military actions on May 10.
