Sanaa - The turmoil in Yemen grew into a regional conflict Thursday, with Saudi Arabia and its allies bombing Shiite rebels allied with Iran, while Egyptian officials said a ground assault will follow the airstrikes.
Iran denounced the Saudi-led air campaign, saying it "considers this action a dangerous step", and oil prices jumped in New York and London after the offensive.
The military action turned impoverished and chaotic Yemen into a new front in the rivalry between Saudi Arabia and Iran.
