The partial US government shutdown entered its third day on Monday without resolution as Democrats continued to demand immigration reforms as part of any funding deal to reopen the government.

Senate Democrats and Republicans agreed to a package of five spending bills on Thursday, but stripped out a sixth bill on full fiscal year funding for the Department of Homeland Security (DHS).

The Senate instead approved a two-week funding for the DHS that gives lawmakers more time to work out disputes over its long-term budget.

Democrats want changes to the immigration enforcement operation, including requiring agents to wear body cameras turned on and to not wear masks.

The package approved by the Senate must now be cleared by the House of Representatives before it is sent to President Donald Trump's desk for signature.
