Yemen’s Houthi rebels fired two ballistic missiles from the capital Sanaa that landed inside Yemeni territory, the Saudi-led coalition said Tuesday. 

Coalition spokesman Col. Turki al-Maliki said the provinces of Amran and Saada in northern Yemen were hit with air attacks in the latest violation by the Iran-aligned Houthi group of the unilateral cease-fire. In early April, the Saudi-led coalition announced the fighting pause, which the Houthis rejected, to allow for UN-brokered negotiations between the two parties amid the coronavirus outbreak. 

Maliki said Houthi forces have violated the cease-fire 2,400 times, using light and heavy weapons in addition to ballistic missiles. Last month, the rebels launched a number of missiles in the direction of the Saudi capital Riyadh as well as Jazan, Asir and Najran near the Yemeni border.

Yemen has been ravaged by war since 2014, when the Houthis, backed by Iran, took control of the capital Sanaa and captured large swaths of the country from pro-government forces, on whose behalf the Saudis and a group of 20 Arab allies militarily intervened in March 2015.
