Houthis accuse Saudi-led war jets of dropping sound bombs on Yemen's capital

Residents in the Yemeni capital Sanaa, which is under control of Shiite Houthis, said they heard sounds of four huge explosions rocking the capital on Sunday.

The explosions came simultaneously with hundreds of supporters of Houthi fighters and their allies loyal to former President Ali Abdullah Saleh celebrating the "26 anniversary of Yemen's national unity day" in Sabeen area near the presidential palace south of the capital.

Rebel-controlled state Saba news agency accused Saudi-led coalition of dropping sound bombs on Nahdayeen mountain on the vicinity of the presidential palace and on Noqum mountain in Sanaa.

North and South Yemen were peacefully unified in 1990, however their relationship deteriorated in 1994, after four-month civil war that ended as northerners overran the south.

The southerners have long complained of being marginalized, as pro-secession protests are rising in the south after the Shiite Houthi rebels and Saleh militants waged a fierce war earlier last year against several cities in the south.

They stormed the southern port city of Aden, forcing internationally recognized President Abd-Rabbu Mansour Hadi and the legitimate government into exile and killing thousands of Southerners and displaced over two millions others.

In July, 2014, a mostly Arab coalition forces led by Saudi Arabia drove the rebels out of Aden and three other major southern provinces after months of war that inflected heavy losses among the rebels.

The Iran-allied Shiite Houthi group and forces loyal to Saleh stormed the capital Sanaa and other cities in September 2014, dissolved the government and expelled President Hadi on allegations of combating "corruption."

The civil war has escalated since then, leaving more than 6,000 killed so far in ground battles and airstrikes, half of them are civilians.

The warring parties now have been in talks in Kuwait since last month under the auspices of the UN to end the war.

The talks is the third of its kind since the conflict began after Houthi militias stormed Sanaa and expelled Hadi in September 2014. Previous peace negotiations had failed to end hostilities.

The government delegation said on Saturday that it will give the peace talks in Kuwait the "last chance," four days after the delegation suspended participation in the talks in protest after the opposition delegates refused to comply with the UN Security Council Resolution 2216 that orders them to withdraw from the capital and disarm.
