(CNN) The US Embassy in Haiti warned its citizens Saturday to stay inside amid continued demonstrations in the capital of Port-au-Prince and a northern city following a fuel price hike.

Protesters have been demonstrating this week against a sharp rise in fuel prices ordered by the government.

Prime Minister Jack Guy Lafontant on Saturday announced a temporary stop to the price increases and appealed for calm. Prices for gasoline were to rise 38% while diesel prices were to go up 47% and kerosene 51%, the Haitian daily newspaper Le Nouvelliste reported.

An estimated 120 American and 100 Haitian guests are staying in a Port-au-Prince hotel where demonstrators earlier tried to set fire to the hotel and get past security, said Stacy Librandi Bourne, an emergency medical professional from HERO Client Rescue who is at the Oasis Hotel.

After the Prime Minister's announcement, the situation calmed down, she said.
