Hundreds of police officers were deployed to the streets of Yemen's capital city of Sanaa on Saturday.
Officers said the security authorities are working hard to restart their duties and drive the militants out of the capital.
"It is not good to continue to see the capital without police or rather under militias. If we don't act, nothing will change," one officer said.
With support from the forces loyal to former president Ali Abdullah Saleh, the Houthi militants ousted the UN-backed government and seized power in late 2014.
They have since been controlling the capital and northern regions.
Meanwhile, the deployment of the police coincided with reports that the Houthi militants have been deployed to secure the gates of the capital in preparation for possible battle with the pro-government forces.
The battles between the pro-government forces and the Houthis on the capital's border with Marib province have been continuing for weeks.
Lately, military sources said the battle to retake Sanaa was close.
Moreover, the Saudi-led coalition has intensified airstrikes against Houthi forces and weapons depots in Sanaa in recent days.
The coalition has been bombing the country since March. So far, it helped the government to retake southern regions in months ago.
It is also continuing to support the government to retake key provinces including Taiz where battles have been raging for around two weeks.
