Bridge strike justification: US officials say the bridge bombed in Iran was used to transport materials for Iranian military drones, Al Jazeera’s Rosiland Jordan reported from Washington, DC. But Iran insists the bridge was civilian infrastructure, which — if true — would make the attack a violation of international law. Casualties and damage: The human toll continues to rise, with at least 2,076 people killed and 26,500 wounded in Iran since the start of US-Israeli attacks. Iran’s Foreign Ministry says more than 600 schools and education centres have been hit since February 28. Iran’s retaliation: Iran’s military says the war will continue until its enemies face “humiliation” and “surrender”, specifically cautioning the US against a ground invasion. Iran’s Foreign Ministry: A spokesperson declared, “What is important for the Iranian nation is to defend itself against this aggression, and we are ready for any type of attack, including a ground attack.” War diplomacy
