Tensions are high in the Gulf after Iran last week renewed threats to close the strategic Strait of Hormuz — the route for one-fifth of the world's oil — in retaliation for tighter sanctions over Iran's nuclear program.
The U.S. recently boosted its naval presence in the Gulf with additional minesweepers and other warships. The Pentagon said Monday it is sending another aircraft carrier to the Middle East several months early to ensure it has two carriers continuously in the region.
Guest workers from India and other South Asian countries have flocked to the Gulf for decades in search of better paying jobs. Many are employed as low-skill workers in industries such as fishing and construction.
