**Saudi aircraft have attacked Shia rebels in northern Yemen following Wednesday’s killing of a Saudi security officer in a border area, reports say.**The Saudi planes and helicopters had targeted strongholds of the Houthis along the Yemeni side of border, the London-based newspaper Elaph said.
The rebels said the planes had struck four locations using phosphorus bombs.
The attacks came after a Saudi security officer was killed and 11 were wounded in a cross-border raid by the rebels.
The Houthis said on Wednesday that they had taken “full control” of a mountainous section of the border region of Jabal al-Dukhan.
The Yemeni government has been waging a campaign against the Shia group since 2004.
The Houthis have long accused Riyadh of supporting the Yemeni government in attacks against them.
In October, there were clashes between Houthis and Saudi security forces near the border.
Yemen is one of the world’s poorest countries and analysts question the ability of the government to assert full control over the country.
