Around 50 people were killed in the attacks, according to the Houthi movement's spokesperson, who did not specify whether they were injured or dead.
Fighting between the Houthi movement - which controls large parts of Yemen - and Saudi Arabia has escalated in recent weeks. The Houthi movement has also announced that it is carrying out a military offensive in Yemen aimed at the strategically important Bab al-Mandab Strait.
The city of Taiz is still controlled by the internationally recognised government, whose seat is in the southern city of Aden, but the Houthi movement appears to have set its sights on gaining full control of Taiz.
At the same time, the movement has intensified attacks on targets in Saudi Arabia and its oil industry.
