The so-called "Tanker War" involved American naval ships escorting reflagged Kuwaiti oil tankers through the Persian Gulf and the strait after Iranian mines damaged vessels in the region. It culminated in a one-day naval battle between Washington and Tehran, and also saw America accidentally shoot down an Iranian passenger jet, killing 290 people.
Mourners tossed flowers from a helicopter and a ferry into the Persian Gulf off the coast of Iran on Tuesday to mark the 30th anniversary of the U.S. Navy shooting down an Iranian commercial airline, which killed 290 people.
