Warplanes from a Saudi-led alliance bombed two houses in the Yemeni capital Sana'a on Tuesday, killing at least 20 people, medics and local officials said.
"Two missiles hit the two houses in the Asbahi district in southern Sana'a, destroying them, killing 20 people and wounding others," a medic said.
A local official had earlier said that a hotel in the same district had been hit.
