RIYADH, Saudi Arabia — In the fraught divide between Sunni and Shia Muslims of the Arab world, the tiny island state of Bahrain is the next crucible of combat.
Unprecedented pro-democracy protests there by the Shia community have had a longer reach than what would normally be the case in a country of only 738,000 for one simple reason: Bahrain’s close ties to its huge neighbor, Saudi Arabia.
The two countries are linked by a 16-mile, multi-lane causeway and by the shared commitment of their Sunni ruling royal families to remain in power. Oil-rich Riyadh also financially supports petroleum-poor Bahrain.
