Iran targets Gulf states in response to US strikes, testing fragile ceasefire

Despite a fragile ceasefire, tensions between the United States and Iran remain high, with both sides accusing each other of violating the truce. Tehran says it has carried out a third consecutive day of retaliatory strikes against US military sites in the Middle East, while Washington has warned that any renewed escalation could trigger overwhelming retaliation. President Donald Trump has threatened to "annihilate" Iran if full-scale conflict resumes, and Iranian officials have responded by saying they are prepared to abandon peace negotiations altogether, raising fears that the ceasefire could quickly collapse into a wider war.
