World Trade Centre remains buried in Kabul ceremony

A small piece of the World Trade Centre has been buried under the flagpole at the US Embassy in Kabul.

The piece was brought by New Yorker Kyle Aldrich who worked in wall street and lost friends in the attacks.

Brad Hanson, the acting US ambassador to Afghanistan, announced at the ceremony that September 11 would from now on be known as Patriot Day.

He was speaking on behalf of George Bush and urged every American to take a moment of silence each year on this date.

A steel-gray marble headstone marked the resting place of the remains brought from the ruined World Trade Centre with the Inscription: "We serve because they cannot."

"It is clearly a conglomerate of different pieces of glass and cement fused together, like a cluster or something," Mr Aldrich said. "It is just dark, black and red blood and dust. It looks like an ooze or coating of blood."

Mr Aldrich had worked at Salomon Smith Barney until January last year, when he resigned to join the Marines. Many of his friends had worked at Cantor Fitzgerald and Morgan Stanley. Some died and many more had escaped.

Another Marine, also of the 3rd Battalion, 8th Marines, Capt Farrel Sullivan, went to New York after a tour of duty in Afghanistan to collect the piece. Together they arranged for its burial in Afghanistan.
