Facebook has launched a Marketplace feature to let people buy and sell items locally, in a move that could rival sites like eBay and Craigslist.
The new feature will debut in the US, the UK, Australia and New Zealand.
A smartphone app will be made available in the next few days with a desktop version due in the coming months.
The new feature puts Facebook in direct competition with increasingly popular local online selling platforms.
The social media site is already being used for selling and buying via Facebook groups.
