Colonial Pipeline said Monday it had begun a phased restart of a giant US gasoline pipeline and hopes to restore operations by the end of the week. The pipeline company said operations were being "brought back online in a stepwise fashion" after Saturday's complete shutdown due to a cyberattack. While "the situation remains fluid and continues to evolve," the company said it has a goal of "substantially restoring operational service by the end of the week." jmb/hs
