Saudi-led warplanes extended air strikes on Iranian-backed Houthi militia in the Yemeni capital Sanaa on Friday, residents in the area said.

They told Reuters that the strikes focused on the presidential compound district in Sanaa, which the rebels seized in September, and Houthi military sites in mountainous areas on the outskirts of the city.

A Saudi-led coalition intervened in Yemen's civil war eight weeks ago to try to roll back Houthi advances across the Arabian Peninsula country and restore exiled President Abd-Rabbu Mansour Hadi in power.

Sanaa residents said air strikes also continued overnight on fighters loyal to former president Ali Abdullah Saleh who are allied with the Houthis in the conflict.

There were also 10 air raids overnight on Houthi and pro-Saleh forces in the oil-producing province of Marib, according to residents in the region.

In Saada province which borders Saudi Arabia in northwestern Yemen, the Houthis said they had seized several Saudi-controlled military sites and taken weapons and equipment there.  

Saudi citizen killed in rocket attack  

A cross border rocket attack launched from inside Yemen killed one Saudi citizen and wounded two others on Thursday in the southern province of Dhahran, Saudi Arabia's state news agency (SPA) reported.

"At 18:30 on Thursday the civil defence sent a communiqué stating that the village of al-Hosn in Dhahran faced [an attack] by military rockets from inside Yemeni territory, which resulted in the death of a citizen and injury of two others," SPA said late on Thursday.

The Saudi-Yemen border has in some places become a front line between the kingdom and Houthi rebel group that a Saudi-led Arab alliance has been bombing for eight weeks.

Earlier this week, the Houthis' Al Masira TV channel broadcast footage it said showed its fighters entering a Saudi border post after being fired on by Saudi tanks and helicopters.
