The Saudi-led coalition backing legitimate government in Yemen stated late on Wednesday that its joint forces had carried out a qualitative operation targeting camps and arsenals of the Iranian-backed Houthi rebels.
Targeting was in compliance with international Human Law and conventional rules, after all protective measures necessary had been taken to protect civilians."
The camps have been used by Houthis to "prepare and arm combatants and then deploy them into Hodeida City," Colonel Turki al-Maliki added.
In Dhamar, 100 kilometers south of Sana'a, a camp was targeted before forces' movement towards Hodeida, leaving the camp destroyed and large numbers of militiamen killed, Saudi Press Agency quoted Maliki as saying.
Operation is not in conflict with Stockholm Agreement, he said noting that Hodeida ceasefire has been "deliberately violated hundreds of times, leaving tens of civilians and military men killed and hundreds injured."
Houthi violations included destruction of private and public properties, obdurately refusal of demining acts to facilitate relief convoys, and obstruction of UN relief groups and NGOs, according to Maliki.
Coalition spokesman accused the rebels of persistent "aggressive and terrorist acts threatening world trade navigation routes through spreading afloat mines and drone explosive-laden boats."
He reiterated his leadership's commitment to the core role in keeping peace and stability in Bab el-Mandeb and southern Red Sea.
Parties to the nearly 4-year war in Yemen, after 8 days of peace talks in Sweden, agreed on the 13th of last December to cease fire in Hodeida, to withdraw all forces from the port city and ports of Hodeida, Salif and Ras Isa.
But the UN-brokered Stockholm Agreement is facing many challenges and difficulties to implement on ground, leading the UN Security Council to adopt a resolution deploying a 75-manned mission led by Cammaert to monitor the truce.
The western port city of Hodeida, on fringes of which pro-government joint forces are positioned, is under Houthi control, along with the Yemeni capital of Sana'a and most populated areas in the north.
On Wednesday, Houthi forces spokesman Yahiya Sari'e accused the Saudi-led coalition of unprecedented escalation through launching 15 airstrikes on Hodeida City, where truce has been supposedly in effect under Stockholm pact.
Nine airstrikes targeted Marabit area to the east of Jarrahi District, one on Salif crossroads, one on Kadan and four on Ma'ashoor of Sokhna District, Sana'a-based Houthi-run Saba quoted Sari'e as saying.
He also accused coalition-backed joint forces of continuing violations of Hodeida truce, while "Houthis are adherent to self-control."
Such breaches are not only "challenge to UN resolutions, but also would foil Sweden pact and UN efforts to stop aggression and make peace in Yemen."
Yemen has been racked by an armed conflict that broke out after the Iranian-backed Houthis had ousted the internationally recognized government late in 2014.
The conflict escalated after a Saudi-led coalition had intervened militarily in the country in March 2015 to reinstate the government of President Hadi, pushing the country to the world's worst humanitarian crisis, according to the UN.
