Iran Claims Strike on US Vessel as Hormuz Fighting Escalates
Iran says it attacked a US military vessel that had no people aboard.
Iran said the vessel was trying to enter the Strait of Hormuz.
The United States has not confirmed that the attack happened.
A day earlier, the US military said it struck three Iranian oil tankers.
The US said those strikes came after Iran attacked American warships with missiles.
The two countries started fighting again last week after about a month of calmer conditions.
A ceasefire announced in June did not stop all later attacks.
The Strait is important because many oil and gas shipments pass through it.
Talks about Iran’s nuclear program have also broken down, making the conflict harder to resolve.
Iran said it attacked an unmanned US vessel attempting to enter the Strait of Hormuz.
The United States did not immediately confirm Iran’s claim, which followed US strikes on three Iranian oil tankers.
US Central Command said the tanker strikes followed unsuccessful Iranian attacks on American warships.
Fighting resumed last week after about a month of relative calm, despite a ceasefire announced in June.
The confrontation also involves sanctions, oil shipments, the Strait of Hormuz and stalled nuclear negotiations.
