On the weekend of May 31, the US armed forces conducted strikes on Iranian radar and command-and-control installations after an Iranian missile downed a US MQ-1 drone flying over international waters in the Persian Gulf. The US characterized the actions as primarily 'defensive.' This occurrence highlighted the precarious nature of the current ceasefire and sparked worries that negotiations for a deal might fail before a final agreement is reached. Both parties escalated their actions shortly after the incident but soon returned to discussions.
