RIYADH: The UN Special Envoy for Yemen Hans Grundberg condemned on Tuesday an attack that claimed the lives of two Bahraini military personnel and injured several others in Saudi Arabia on Monday. Bahrain’s military said on Monday that one officer and one soldier had been killed in a drone attack perpetrated by the Houthis. Grundberg expressed concern over continued military tensions at the Yemeni border and on several frontlines in Yemen over the past months that have led to casualties, including civilian loss of life. He warned that any renewal of offensive military escalation risks plunging Yemen back into a cycle of violence and undermines ongoing peace efforts.“Continued flare-ups of fighting demonstrate the fragility of the situation in Yemen,” the special envoy said. “We have been in touch with all sides to urge them to exercise maximum restraint at this critical time, and to use dialogue to resolve differences and diffuse military tensions,” he added. Grundberg warned that “the minimum level of trust required for constructive dialogue is hard-earned, but easily lost.” He emphasized the need for decisive steps towards a sustainable nationwide ceasefire and the resumption of an inclusive political process to end the conflict. He also offered his condolences to Bahrain and his wishes for the swift recovery of the injured. The US embassy in Saudi Arabia also condemned the attack. “Such attacks are unacceptable and threaten the longest period of calm since the war in Yemen began,” it said in a statement.
