Wales' political leaders have paid tribute to those who died and the families who lost loved ones in the 9/11 terror attacks, twenty years on from the atrocities.
First Minister Mark Drakeford said his thoughts were with all of those marking the "sombre milestone".
Writing on Twitter, Mr Drakeford said: "Today marks 20 years since the 9/11 attacks - an event that shook the world and remains etched on all our memories.
"My thoughts are with the friends and families of all those who lost their lives during the attacks and in the aftermath as they mark [this] sombre milestone."
Andrew RT Davies, leader of the Welsh Conservatives, also paid tribute.
"20 years on from the September 11 attacks , my thoughts are with those who lost their lives, as well as the survivors and the emergency services who risked so much to help others."
Jane Dodds, leader of the Welsh Liberal Democrats, extended her tribute to those killed in the conflicts that followed the 9/11 attacks.
Cities across the world plan to fall silent on Saturday to remember the 2,977 people who died in what were the most devastating terrorist attacks in American history.
In the US there will be an official service of remembrance at Ground Zero, the site where the Twin Towers fell, which will be attended by US President Joe Biden and First Lady Jill Biden.
Ceremonies will also take place at the Pentagon and in Pennsylvania where the flight United 93 came down, after passengers managed to fight back against the hijackers.
It will take three hours to read the names of the dead.
