Gardens are being searched by police in an Edinburgh neighbourhood in a bid to find firearms and drugs which are thought to be buried there.
Officers said they were searching in the area of Broomhouse Square and Broomhouse Loan following a tip-off.
Leaflets are being handed out to local residents informing them of the police operation, which is happening all day.
Officers said residents might be unaware the firearms had been buried in their garden.
The operation is being led by the Edinburgh Serious and Organised Crime Unit, supported by local officers.
A Lothian and Borders Police spokesman said: "Throughout the day we will be asking residents for permission to access their property, and we will aim to cause as little disruption as possible.
"We are acting on information that there may be firearms hidden within a garden in the area, possibly without the knowledge of the homeowner.
"We are keen for any new information that can assist our inquiries, and rest assured that any calls we receive will be treated in the strictest of confidence."
