The U.S. State Department is strongly urging U.S. citizens to consider carefully all visits to Haiti.

A travel warning issued Monday cites a “critical crime level,” a cholera outbreak and inadequate infrastructure.

The U.S. Embassy in Haiti says there are reports of demonstrations in downtown Port-au-Prince and all trips to the capital should be postponed until further notice.

The revised advisory comes as Haiti's President Michel Martelly struggles to install a new government.

Recently, Haitian lawmakers rejected President Martelly's second pick for prime minister. The political wrangling continues to hamper efforts to rebuild Haiti after the devastating 2010 earthquake.

President Martelly, a former pop music star, was elected in March with no political experience, and took office in May.
