Attacks on Tankers in Hormuz Hit Highest of Any Week Since Start of Iran War, Sources Say

Maritime security sources tracking incidents said attacks on tankers in the Strait of Hormuz last week were the highest of any week since the Iran war began. In the week of September 28 to October 5 there were at least 12 attacks on oil, liquefied natural gas and liquefied petroleum gas tankers around the strait, the highest single-week number since the US war with Iran began on February 28, while separate IMO data showed nine incidents in the same week. The US Navy-led Joint Maritime Information Center said attacks, attempted attacks and harassment activity including drone overflights, surveillance and VHF hailing by Iran's Revolutionary Guards have persisted, and India's foreign ministry said 12 crew members were injured when an unknown projectile struck the Panama-flagged oil tanker On Peace in the strait.

Why it matters: The attacks bear on the briefing's energy security theme, since they coincide with a Gulf export push above pre-war levels and cloud the outlook for sustained flows through a key transit lane.
