From the London Mail [caution, tabloid]:
The United States military has deployed the aircraft carrier USS Nimitz to the Persian Gulf alongside other warships in order to provide ‘combat support and air cover’ for soldiers withdrawing from Iraq and Afghanistan.
The deployment comes as tensions in the region have ratcheted up following the assassination on Friday of a top scientist who headed Iran’s nuclear program. The decision to deploy the Nimitz to the Persian Gulf was made before the killing of Mohsen Fakhrizadeh-Mahabadi – a physics professor and former officer in the Iranian Revolutionary Guard.
