Multiple sources have reported that one American service man was killed and a second wounded in what was characterized as an insider attack carried out by a member of the Afghan National Defense and Security Forces.
"Devastating news. North Ogden Mayor Brent Taylor was killed today while serving in Afghanistan", Cox said.
"We are devastated by the loss of our Mayor and friend, Brent Taylor", the city said on its Facebook page. Taylor was the first known sitting mayor in Utah history to temporarily step down from elected office, to deploy on a combat operation overseas, state news outlets report. "I'm struggling for words".
"The entire Herbert family mourns with this soldier's family and we pray that their burdens may be lifted, and that the hearts of all Utahns will reach out to comfort them in their grief", the governor added.
Taylor became the city's mayor in 2013.
Taylor in January when he was being deployed told local media that he was assigned to serve on an advisory team training the staff of an Afghan commando battalion.
The other service member, who was wounded, is undergoing medical treatment and in stable condition, according to the North Atlantic Treaty Organisation statement.
"Initial reports indicate the attacker was a member of the Afghan National Defense and Security Forces", Resolute Support revealed in an official press release."Initial reports also indicate the attacker was immediately killed by other Afghan Forces".
This is being seen as the latest so-called "green-on-blue" attack, in which members of the Afghan forces have killed USA or coalition soldiers.
Taylor previously served two tours of duty in Iraq as a convoy security commander and then as an adviser to the Iraqi intelligence agency, according to a city council biography.
The city of North Ogden is planning a memorial for Taylor, but details of the event have not been released yet.
Over the past 10 months, Taylor posted periodic updates of his Afghanistan service to Facebook, often sounding and looking optimistic.
Hundreds of residents of North Ogden lined the street to see him off as police escorted him and his family around North Ogden, a community of about 17,000.
"Brent Taylor was a dynamic individual", said Brent Chugg, who has served as North Ogden's temporary mayor during Taylor's deployment. On Oct. 18, an insider attack in Kandahar led to the death of two top Afghan security officials and also wounded Brigadier General Jeffrey Smiley, the top us general in southern Afghanistan.
"I hate this", Cox wrote.
'And that whether the Republicans or the Democrats win, that we all remember that we have far more as Americans that unites us than divides us. "We feel blessed to have had him as our mayor".
