US and Iran exchange fire for a second day, undermining shaky ceasefire

Summary

The United States and Iran traded air ​attacks for a second straight day on Thursday, with President Donald Trump vowing further strikes if Tehran does not immediately agree to a peace deal. The escalation in hostilities began this week with Monday's downing of a US Apache helicopter near the Strait of Hormuz, which sparked a series of tit-for-tat attacks across Iran and on US bases around the region.
