Hundreds of Iraqis protesting against Israel’s attacks on Gaza are blocking oil tanker trucks from crossing into Jordan, saying they will not allow Iraqi oil to be exported to countries that have peace agreements with Israel, Reuters reports.

Some 800 supporters of Iraq’s Popular Mobilisation Forces (PMF) began a sit-in on Friday at Iraq’s main border crossing with Jordan, to express solidarity with Gaza and call for an end to Israel’s bombardments and blockade.

Iraq transports about 15,000 barrels per day (bpd) of crude oil in tanker trucks to Jordan, one of the few Arab states that has a peace treaty and a long history of close security ties with Israel.

Preventing the trucks from crossing “is meant to prevent Iraqi oil, which reaches them (Jordan) at a subsidised price, from going to countries that have normalized relations with Israel,” said protester Karar al-Zamili.
