brick

Blaenavon Ironworks' Cast House was recently closed to the public after a visual display was vandalised and bricks thrown from the top of a tower.

It advised some of the construction debris dumped at the site - concrete, bricks and glass - could remain in place as those materials do not cause water pollution.

Buildings in Afghanistan also tend to be made of timber, mud brick or weak concrete, which are not quake-resistant.

"It was coming down the side street off the side of the pub like a river. It was bringing bins, bricks and debris down the street."

The brick and wrought-iron balconies were twisted in the blast, some hanging by a thread.
