Investigation after scrapyard fire in Inverkeithing
An investigation is under way after a fire in a scrap metal yard in Fife, which caused smoke to drift across the Firth of Forth.
The blaze at Robertson Metals in Inverkeithing led to a huge plume of smoke that could be seen for miles.
It took firefighters seven hours to bring "the major incident" under control.
Health agencies have been testing smoke particles for toxins but said the risk to public health was low.
The fire broke out at about 0530 BST and spread smoke for miles.
No-one was injured but people as far away as South Queensferry on the other side of the river Forth were being asked to keep their windows and doors closed as a precaution.
Earlier, Herbert Alan, 77, who lives six miles away at Ratho station, told the BBC Scotland news website: "I have been watching plumes of smoke billow up into the sky for about two hours now.
"It is certainly a big fire, with the smoke spreading out like a cabbage head which is gradually moving east in the wind.
Mr Alan added: "The smoke cloud looks like it has risen to about 1,000ft."
A spokesman for the Scottish Environment Protection Agency (Sepa) said: "Operational staff are on site to assess the impact of the fire on the surrounding environment, and Sepa scientists are being deployed to monitor the resultant smoke plume's composition and direction of travel.
"Sepa will continue to work with the fire and rescue services, the police and other partner agencies to try to minimise any impact from the fire on the local environment."
