9/11 anniversary: Carwyn Jones sends condolences to US
First Minister Carwyn Jones said 9/11 saw "the best and worst of humanity" as he sent his condolences on the 10th anniversary of the attacks.
"I will never forget the bravery, determination and total selflessness of the firefighters...who made the ultimate sacrifice," he said.
Plaid Cymru leader Ieuan Wyn Jones said it "left an indelible mark on us all".
The first minister wrote his message of remembrance to the US ambassador to the UK.
The Welsh Government will remember all those who lost their lives in the terrorist attacks at a special commemorative concert at the Lincoln Center in New York.
The concert will include two works by Welsh composer Karl Jenkins - The Armed Man: A Mass for Peace and For the Fallen: In Memoriam Alfryn Jenkins.
Recalling the "horror and disbelief" of the attack on the World Trade Center twin towers in New York in 2001, the First Minister said: "The people of Wales stand with the people of America in showing a united front against terrorism while promoting and defending shared values of tolerance, understanding and mutual respect.
"All the communities and faiths of Wales are committed to these values - they unite our society."
He added he was pleased that the Welsh Government is able to make its own contribution to activities commemorating the attacks.
"The concert in the Lincoln Center will be an opportunity for everyone to join together in a period of remembrance and reflection, promoting the causes of peace and hope," he said.
'Changed the world'
"I wish everyone involved the very best of luck for what I'm sure will be a very poignant and thought-provoking concert. "
Outgoing Plaid Cymru leader Ieuan Wyn Jones said he hoped the anniversary could provide "new impetus for achieving peace throughout the world".
In a joint statement, Archbishop of Wales, Dr Barry Morgan, and the Secretary General of the Muslim Council of Wales, Saleem Kidwai, said the after-effects of the attacks on the New York World Trade Centre and on the Pentagon 10 years ago "changed the world".
"Here in Wales, a determination quickly emerged to challenge the climate of heightened fear, suspicion and distrust created by so-called religious terrorism and the response to it," they said.
"Working together has broken down barriers, built positive relationships, and underlined a passionate commitment to create a more harmonious society."
