Oil drops as Saudis signal likely supply boost

Global oil prices fell Friday after top producer Saudi Arabia signaled a likely boost in supply as soon as the third quarter, and world stock markets were mixed over the sudden US move to cancel the summit with North Korea. Saudi oil minister Khaled al-Faleh said at an economic conference in Russia that a gradual output increase could happen in the second half of the year to prevent any supply shocks, according to the RIA Novosti agency.
