The cables, north of the Egyptian port of Alexandria, were snapped Wednesday just as the working day was ending in India, so the full impact was not apparent until yesterday. There was speculation a ship's anchor might be to blame. The two cables, named FLAG Europe Asia and SEA-ME-WE 4, are in close proximity.
Egyptian officials said initial attempts to reach the cables were stymied by poor weather. Repairs could take a week.
Bangladesh, Pakistan, Egypt, Qatar, Saudi Arabia, the United Arab Emirates, Kuwait, and Bahrain all reported trouble.
