The United Nations is ready to get into the Syrian city of Raqqa after so-called Islamic State (IS) was driven out after three years.
Aid workers have said it may take years before they can return to their homes.
A US-backed alliance of Syrian fighters says it has full control of the city.
Operations were under way to uncover jihadist sleeper cells and remove landmines from the last areas of Raqqa, Syrian Democratic Forces (SDF) spokesman Mustefa Bali said.
The four-month assault against IS destroyed Raqqa's civilian infrastructure and homes, humanitarian agencies say.
