Two Saudi bases in Najran hit by Yemeni missiles

The retaliatory attack was launched with the support fighters of the Yemeni Houthi Ansarullah movement, Yemen's Arabic-language al-Masirah news website reported on Sunday.

Earlier, Yemeni army and Houthi fighters fired missiles at Saudi mercenary rally point in Lahij’s Kahboub district, killing and injuring a number of them.

Another site belonging to the Saudi mercenaries also came under similar attacks in the kingdom’s southwestern region of Jizan.

Such attacks are part of a drive by Yemeni forces and allies to avenge Saudi Arabia’s relentless military aggression against the country.

Meanwhile, Saudi warplanes have increased their relentless airstrikes on Yemen, just one day after an UN-backed ceasefire expired.

At least six civilians were killed as Saudi jets used internationally-banned cluster bombs on the Baqim district in Sa’ada province.

Air raids were also launched on civilian facilities in the capital Sana’a's Nihm, Naqim and Hafa districts and on a water storage facility in western port city of Hudaydah.

Attacks were also launched on the provinces of Ta’izz, Hajjah and Ta’izz.

Despite renewal calls by the UN’s Special Envoy for Yemen Ismail Ould Cheikh Ahmed, a 72-hour ceasefire ended on Saturday. The truce was brokered by the UN to allow aid to reach families trapped in areas cut off by the war in the impoverished country.

More than 10,000 Yemenis have been killed since the regime in Riyadh launched its deadly campaign against Yemen in March 2015. The military aggression was meant to reinstall Abd Rabbuh Mansur Hadi, a staunch ally of Riyadh who has resigned as Yemen’s president.
