The Bahrain Defense Forces said the soldier died from wounds sustained in Monday’s drone attack.
The death toll of Bahraini soldiers killed in an attack blamed on Yemen’s Houthis has risen to three, Bahrain’s state news agency said.
Two Bahraini soldiers stationed in Saudi Arabia were initially confirmed dead in Monday’s drone strike, and a third soldier succumbed to his injuries on Wednesday, the Bahrain Defense Forces said.
The attack occurred as soldiers patrolled Saudi Arabia’s southern border with Yemen.
Bahrain’s Armed Forces announced the death of a third soldier on Wednesday, saying: “We mourn one of our soldiers who was seriously injured and martyred today after the Houthi attack on Saudi Arabia’s southern border.”
Bahraini government agencies identified the soldier as Warrant Officer 1st Class Adam Salem Naseeb and said he “gave his life bravely in the line of duty.”
There was no immediate comment from the Houthi rebels regarding the incident.
Bahrain has demanded that Iranian-aligned rebels hand over the perpetrators of the attack, which comes amid efforts to reach a deal with Saudi Arabia and the Houthis.
The Saudi-led coalition intervened militarily in Yemen in 2015 to support Yemeni government forces against the Houthis. The war is thought to have killed hundreds of thousands of people, most of them indirectly, and left 80 percent of the population dependent on aid.
Drone attacks mark a significant escalation after more than a year of relative calm in Yemen, brokered by the United Nations, as peace efforts gain momentum.
Last week, a Houthi delegation concluded its visit to the Saudi capital, Riyadh, following an official invitation sent by Saudi Arabia and following five days of talks with Saudi officials.
It was his first official visit to Saudi Arabia since war broke out in Yemen in 2014, after the Houthis ousted the Saudi-backed government and seized much of the country, including the capital Sanaa.
Some progress was made on two key conditions, including a timeline for the withdrawal of foreign troops from Yemen and a mechanism for paying public wages, people familiar with the meeting said.
