This is the second day Saudi Arabia has struck by air targets in Yemen as they pursue Houthi rebel targets in their offensive in Yemen.
Last night, Arab foreign ministers agreed to a draft resolution for Egyptian and Saudi Arabian troops to lead a ground operation in Yemen against the Shite rebels.
The unified military force was announced by the Arab League's general Secretary in Cairo.
Iran, who is largely seen as a fundamental supporter of the Houthi rebels has demanded an immediate halt to the Saudi-led strikes. The Saudis are Suni in their orientation.
Earlier this week the Houthi rebels seized control of the strategically important city of Taiz in southern Yemen.
The takeover sparked protests among local people, at a time of escalating violence by rival armed groups, including Islamic State militants.
The rebels appear on the verge of taking over the key port city of Aden in the country's south and had already driven out Yemen's embattled president Abed Rabbo Mansour Hadi who has fled to the Saudi capital of Riyadh by sea.
Reports say the Saudi kingdom has deployed 100 fighter jets, and 150,000 soldiers along with navy units.
The imminent fall of Aden has pushed Yemen further towards a violent Civil War – with the Islamic State also waging war against both Yemeni factions.
The regional fear is that a proxy war is going to be fought in Yemen, the poorest country of the Middle East – between the regional powers of Arab Suni and Shai Muslims.
