Iran is halting oil tanker traffic through the Strait of Hormuz after Israel attacked Lebanon, according to the semi-official news agency Fars.

Pakistani Prime Minister Shehbaz Sharif had earlier stated that Lebanon was included in a ceasefire agreement involving Israel, the United States and Iran. However, the Israeli military has said its attacks on Hezbollah targets in Lebanon will continue.

Israel on Wednesday carried out what it described as its largest strikes on Lebanon since the start of the war.

Fars also reported that only two oil tankers have been allowed to cross the strait since the ceasefire came into effect.

Meanwhile, a key oil pipeline used by Saudi Arabia to transport crude to the Red Sea — bypassing the Strait of Hormuz — has been attacked, according to three separate news outlets.

A pumping station along the 1,200-kilometre East-West pipeline was targeted at around 1:00 p.m. local time on Wednesday, two sources told the Financial Times.

One of the sources said the pipeline was struck by a drone.
