Second US aircraft carrier deployed to gulf

The US navy has deployed a second aircraft carrier to the Persian Gulf amid rising tensions with Iran over its nuclear programme.

Cmdr Amy Derrick-Frost, of the Bahrain-based 5th Fleet, said that the deployment of the nuclear-powered USS Enterprise along with the Abraham Lincoln carrier strike group marks only the fourth time in the past decade that the navy has had two aircraft carriers operating at the same time in the region.
