(AP) — The United States military said Tuesday that it carried out strikes on Iran following the crash of an Army helicopter near the Strait of Hormuz that President Donald Trump blamed on the Islamic Republic. Tehran vowed to respond.

The strikes were “a proportional response to unjustified Iranian aggression,” US Central Command said on social media.

Iranian state media reported that explosions were heard on Qeshm Island in the Strait of Hormuz, a critical shipping lane that Iran has effectively closed during the war, before saying the wave of American attacks in the south had “subsided.”
