The future of the US government's main overseas aid agency has been cast into doubt, with employees locked out and the Trump administration planning to merge it with the US Department of State.
The United States Agency for International Development (USAID) would continue to function as a branch of the state department, but the plan involves a significant reduction in its funding and the workforce, CBS News, the BBC's US partner, reports.
On Monday, Secretary of State Marco Rubio accused USAID's leadership of "insubordination" and said he was now its "acting head".
US President Donald Trump and one of his top advisers, billionaire Elon Musk, have been strongly critical of the agency.
But the move to shut it down could have a profound impact on humanitarian programmes around the world.
