Israeli forces unleashed a series of strikes on the Yemeni capital Sanaa and the western city of Hodeidah on Thursday, according to Houthi-run media, killing at least four people and injuring more than a dozen others.

Air strikes have been reported in two cities in Yemen. Witnesses and governing Houthi rebels said the country's main international airport and a military base were targeted in the capital Sanaa, while a power station in the western port city of Hudaydah was also hit, the AFP news agency reported.

The assault killed at least four people and injured 21 others, the state news agency in Yemen reported. The strikes came after a week of attacks by the Iran-backed militia.
