Saudi Arabia launches Yemen air strikes

"The US has confirmed its support for an extraordinary international military alliance that is emerging to counter Houthi rebel advances in Yemen. 

As Saudi Arabia began pounding the rebels with airstrikes, countries from the Middle East to Pakistan were said to be prepared to commit troops for a ground assault. The US was providing “logistical and intelligence support” to the Saudi-led forces attacking the rebels, the White House announced. Meanwhile the Saudi-owned Al Arabiya news channel said the kingdom had lined up 150,000 soldiers in preparation for a ground offensive, with Egypt, Pakistan, Jordan and Sudan also ready to commit troops."
