The biggest fuel pipeline system in the United States has been shut down following a cyberattack.

The Colonial pipeline ships more than two and a half million barrels of oil a day, from the Gulf Coast and supplies almost half the petrol and diesel for the east coast of the United States.

Emergency powers were invoked to try to avoid fuel shortages.

President Biden says there is no evidence of Russian government involvement but there are some signs that the attack originated in Russia.
