Oil prices continued to climb to hit $85 a barrel on Tuesday, marking their highest level in nearly a month as U.S. strikes on Iranian military targets and disruptions to shipping through the Strait of Hormuz heightened supply concerns.

International benchmark Brent crude rose 2.4% as of 06:35 a.m. GMT, extending its gains since the start of the week to more than 13%.

The U.S. Central Command (CENTCOM) said its latest five-hour operation targeted military sites along Iran's southern coastline, including coastal defense systems, missile and drone facilities, and maritime capabilities.

The targets were located in Bushehr, Chah Bahar, Jask, Konarak, Abu Musa, and Bandar Abbas, according to CENTCOM, which said the strikes were intended to weaken Iran's ability to attack commercial shipping.

U.S. President Donald Trump said American forces were targeting Iran's military capabilities linked to the Strait of Hormuz and reinstating a blockade on Iran and vessels doing business with Tehran.
