PORT-AU-PRINCE, Haiti — Looters pillaged burned and vandalized shops in Haiti’s capital Sunday following two days of violent protests over the government’s attempt to raise fuel prices.

Journalists saw young men stripping shelves bare in some supermarkets that were charred from the protests. Several bodies lay among debris scattered in the streets.

With the situation still chaotic, the U.S. Embassy in Port-au-Prince on Sunday warned U.S. citizens to shelter in place. It noted that many airline flights had been cancelled and said, “The airport has limited food and water available.”

“Telecommunications services, including Internet and phone lines, have been affected throughout Haiti,” the embassy added. “It may be difficult to reach people through normal communication methods.”

American Airlines, which had canceled 10 flights since Saturday, said three of its planes had left Sunday from Port-au-Prince and the northern city of Cap-Haitien bound for Miami and New York.
