As the situation in West Asia escalated, PM Narendra Modi tonight chaired a meeting of the Cabinet Committee on Security to assess the impact on India and the subcontinent.Defence Minister Rajnath Singh, Home Minister Amit Shah and Finance Minister Nirmala Sitharaman attended the meet. Chief of Defence Staff Gen Anil Chouhan was also present as the CCS reviewed potential threat assessment in the wake of the snowballing conflict.The CCS also discussed the issue of Indians stranded in conflict-hit zones and ways to bring them to safety. Apart from the security challenge, the ongoing strikes and counter-strikes between US-Israel forces and Iran pose a potential crisis for essential commodity supply chains, especially oil.Cabinet Secretary TV Somanathan, Principal Secretaries to the PM PK Mishra and Shaktikanta Das and Foreign Secretary Vikram Misri were also present.Experts said 20 million barrels of oil passed through the Strait of Hormuz yesterday, but today the number might be zero after Iran closed down the strait.Twenty million barrels of oil pass through this strait every day. Fifteen percent of all liquefied natural gas globally transits this chokepoint and one-fifth of the world’s petroleum supply moves through a channel just 21 miles wide at its narrowest point between Iran and Oman, experts noted.
