The US government has shut down for the first time in almost seven years after members of Congress failed to agree a last-ditch funding deal.
Hundreds of thousands of federal workers could now be furloughed or laid off, and national parks and museums could close. Previous government shutdowns have also led to air travel disruption due to staff shortages.
The path forward is unclear as both sides have blamed the other for the shutdown. Efforts in the Senate to keep the government funded fell short late on Tuesday despite frenetic negotiations.
President Donald Trump has threatened mass firings and the cutting of some federal benefits that he said were important to Democrats.
Sixty votes are needed in the Senate to pass a government funding bill, meaning that even while Republicans control both chambers of Congress they will need Democratic backing to reopen government.
