The Saudi-led coalition fighting the Houthis said it had destroyed a missile before it took off in Yemen, according to a report on Saudi state TV. The report said the Houthis had meant to use it to attack the gas-rich Yemeni province of Ma'rib.
The Iran-aligned Houthis have rejected a ceasefire proposal made last month by Riyadh because it did not include the lifting an air and sea blockade imposed by a Saudi-led military coalition on the areas they control mainly in northern Yemen.
The conflict, seen in the region as a proxy war between Saudi Arabia and Iran, has caused what the United Nations says is the world's largest humanitarian crisis.
The coalition intervened in 2015 to support Yemen's internationally-recognized government after it was ousted from the capital Sana'a by the Houthis.
