Haifa Mayor Yona Yahav further said that municipality trucks were blocking the entrances to Israel Oil Refineries and Petroleum & Energy Infrastructures, both of which are based on the bay in the northern port city. “From now on, no tankers will have access to the factories,” he said in remarks relayed by his office, which said five factories had been ordered to shut down.
