Iran-US tensions: IndiGo cancels some international flights, issues alerts on others

IndiGo on Sunday issued a travel advisory, alerting of cancellations and subsequent delays, stating that the airline's flight schedules are undergoing certain changes in view of the recent developments around Iran and with the country's rising tensions with the United States.

US-Iran tensions — what's happening?

Iran and US have exchanged sharp warnings this week, fueling tensions between the two nations. This comes after Trump said that America was moving naval warships closer to the region “just in case” he decides to take action. He had earlier warned that an “armada is heading” toward Iran, raising fears of a possible military escalation.

In response to the threats, Iran’s Revolutionary Guard commander Gen Mohammad Pakpour said, “The Islamic Revolutionary Guards and dear Iran stand more ready than ever, finger on the trigger, to execute the orders and directives of the Commander-in-Chief,” reported Nournews, a local news outlet.

Meanwhile, Iran’s Supreme Leader Ali Khamenei has reportedly been moved to a fortified underground shelter in Tehran, sources told Iran International. As per the report, the shelter includes interconnected tunnels designed to withstand possible strikes.

Around two weeks back, Iran closed its airspace to all flights, allowing only international services to and from the country with official clearance. However, it was reopened after just five hours of closure.
