The Saudi-led coalition has started a military operation against the Yemeni Houthi movement after it stepped up cross-border missile and drone attacks on Saudi Arabia, state television reported on Wednesday.
In Yemen, Houthi-run Al Masirah TV reported coalition air strikes on the capital Sanaa, Marib, al-Jouf, al-Bayda, Hajjah and Saada provinces on Wednesday.
The coalition, which has been battling the Iran-aligned movement for five years, will hold a news conference on the operation against Houthi targets that aims to neutralise its military capabilities, Al-Ekhbariya channel and Saudi-owned Al Arabiya TV said.
The alliance intervened in Yemen in March 2015 after the Houthis ousted the Saudi-backed government from the capital, Sanaa, in late 2014. The Houthis say they are fighting a corrupt system.
The conflict is largely seen in the region as a proxy war between Saudi Arabia and Iran.
