DUBAI (Reuters) - Four armed men set on fire a bus transporting workers in Saudi Arabia's oil-producing Eastern Province on Tuesday afternoon, state news agency SPA reported, citing local police.
The attack did not result in any injuries, the report said, without naming the company to which the bus belonged.
It said the men stopped the bus as it was passing through a residential neighbourhood in Qatif, where there has been unrest over the execution of a Shi'ite Muslim cleric.
