An American celebrating his silver wedding anniversary was one of those killed during the Westminster terror attack.

Kurt Cochran, from the western US state Utah, was on the final day of a celebratory trip to the capital with his wife of 25 years when the pair were caught up in the carnage.

They were visiting Mrs Cochran's parents who were serving as missionaries in the London Church of Jesus Christ of Latter-day Saints, according to a crowdfunding page set up for the family.

Mrs Cochran broke her leg, a rib and cut her head, and is recovering in hospital, her sister Sara Payne-Mcfarland wrote on Facebook.

She said: "While we are glad she survived, our hearts are broken and will never be the same after losing our dear uncle, brother-in-law, father. Kurt, you are a HERO, and we will never forget you."

Mr Cochran died "from the injuries he received during the attack in London", his brother-in-law Clint Payne said on Facebook.

In a statement issued by the church on behalf of the family, Mr Payne said: "Kurt was a good man and a loving husband to our sister and daughter, Melissa.

"They were in Europe to celebrate their 25th wedding anniversary, and were scheduled to return to the United States on Thursday.

"Melissa also received serious injuries in the attack, and is being cared for in the hospital."

Mr Payne added: "We express our gratitude to the emergency and medical personnel who have cared for them and ask for your prayers on behalf of Melissa and our family.

"Kurt will be greatly missed, and we ask for privacy as our family mourns and as Melissa recovers from her injuries."

A long-standing family friend of Mr Cochran, Jessica Sellers, told the Press Association: "He was the kindest soul you'd ever meet in your life, he would give you his last penny if you needed it."

The 25-year-old, from Pennsylvania, said: "He was also a very talented man in many aspects but his musical talents were always my favourite as a child.

"I always loved visiting him cause he always had treats hidden just for me... anyone who met him loved him cause of his kind soul and upbeat spirit."

US president Donald Trump said Mr Cochran was a "great American" and said his "prayers and condolences are with his family and friends".

A GoFundMe page set up in aid of Mrs Cochran said that the couple were "self-employed, having built a recording studio business from the ground up over the last 10 years".

"During that time they donated their recording and sound skills to the Summerfest celebration in Bountiful, Utah, to local school productions, and many other worthy causes."
