Messages of shock and devastation have been flooding social media after news of the tragic death of teenage boxer, Rashed Al-Swaisat.
The 19-year-old from Jordan was rushed to hospital after being knocked out in a sickening incident at the International Boxing Association (AIBA) world youth championships in Poland more than a week ago.

Doctors were sadly unable to save the life of the rising star, with AIBA sharing the tragic news of his passing on social media.
"It is with deep sadness that we learned of the passing of Rashed Al-Swaisat of Jordan, who had been admitted to hospital on April 16 further to his fight during the AIBA YWCHs," AIBA said in a statement.
"Our thoughts are with his family, friends and team mates, to whom we offer our sincere condolences."
The Jordanian Olympic Committee (JOC) also confirmed the news and offered condolences to the athlete's family.
"The Jordan Olympic Committee expresses its deep sadness and pain at the death of the national boxing team player, Rashed Al-Swaisat, who passed away yesterday evening, Monday," the JOC said in a statement on social media.
