The United States revoked a temporary sanctions waiver for Iranian oil Tuesday after three tankers were struck in the Strait of Hormuz, raising pressure on Tehran as it negotiates with Washington over ending the Middle East war.
The US Treasury Department canceled a license announced in June that had allowed Iran to produce, sell and deliver crude oil and related products through August 21.
"Iran's actions in the Strait were wholly unacceptable to the United States and will be met with consequences," a US official told AFP.
