DUBAI, June 5 (Reuters) - Bahrain said on Monday it cut diplomatic relations with Qatar, accusing its fellow Gulf Arab state of backing terrorism and interfering in Bahrain's internal affairs.

A brief statement on the official Bahrain news agency said Bahrain, a close ally of Saudi Arabia, was also cutting air and sea contact with Qatar and was giving its citizens in Qatar 14 days to leave. (Reporting by Noah Browning, Writing by William Maclean)
