In an unusual tableau, Saudi Arabia's ambassador to the United States announced the rare military operation by his country at a Washington news conference about a half-hour after the bombing began. The strikes started at 7 p.m. EDT, he said. Loud, house-shaking explosions could be heard in the Yemen capital of Sanaa and fire and smoke could be seen in the night sky, according to an Associated Press correspondent whose home is near the military airbase in the capital. --------- Yemen has always been the Saudi's backwater proxy.
