Tropical Storm Erika left at least 20 people dead when it swept over the tiny island nation of Dominica, officials reported Friday, as the system barreled through the Caribbean.

While crews rushed to search for survivors and clean up scenes of chaos on Caribbean islands, Haitian authorities issued travel restrictions and opened emergency shelters ahead of the storm's arrival.

Ten Venezuelans have been arrested over a shipment of cocaine found in a plane that traveled from Caracas to the Dominican Republic, prosecutors said Thursday.

Five of them were arrested in the airport of the Venezuelan capital -- three military officials, one working in customs and the fifth employed by a state-run security firm.
