Iran could prevent even "a single drop of oil" passing through the Strait of Hormuz if its security is threatened, a naval chief said on Saturday.
Iran will also increase its military presence in international waters, said Ali Fadavi, naval commander in Iran's elite Islamic Revolutionary Guard Corps (IRGC).
"If they (the U.S.) do not obey international laws and the IRGC's warnings, it will have very bad consequences for them," Fadavi said, according to Iran's Fars News Agency.
The U.S. navy has said they will not tolerate any blocking of the strait.
