Fox News reports that “Iran threatened to shoot down two US Navy surveillance aircraft flying close to Iranian territory in the Persian Gulf over the weekend, the latest in a series of recent provocations between Iran and the US military in the region, three US defense officials with knowledge of the incident told Fox News.”

“On Sept. 10, a Navy P-8 Poseidon with a crew of nine and an EP-3 Eries with a crew of roughly 24, were flying a reconnaissance mission 13 miles off the coast of Iran, through the Persian Gulf, Strait of Hormuz and Gulf of Oman, according to officials who call the boundary Iran’s ‘black line.'”

“Iran’s territorial waters—like all nations–extend 12 miles into the sea, according to international maritime law.”
