Waco firefighters fear toxic fumes after fertiliser plant

Several people have been injured and many others are trapped in burning buildings after a huge explosion at a fertiliser plant near Waco in the US state of Texas.

TV images showed streams of emergency vehicles descending on the site following the blast at 19:50 (00:50 GMT).

Dean Wilson from the Texas Public Safety Department said firefighters were having difficulty tackling the blaze because of toxic fumes being emitted from the site.
