'Massive strike' with ship-launched missiles and jets - AP report
US officials quoted by the Associated Press spoke of a massive retaliatory strike using warship-launched Tomahawk cruise missiles and fighter jets.
The Houthi targets included logistical hubs, air defence systems and arms depots, they said.
AP journalists in Sanaa heard four explosions, but saw no sign of warplanes. Two residents of Hudaydah said they heard five strong explosions.
It is the first US military strike against the Houthis in Yemen since the Iran-backed group began firing drones and missiles at cargo ships in the Red Sea in November.
