Rescue workers in Haiti struggled to reach isolated towns on Haiti’s southern peninsula and learn the full extent of the death and destruction caused by Hurricane Matthew as the powerful storm lashed at the Bahamas on Wednesday and triggered large-scale evacuations along the U.S. East Coast.

At least 16 deaths were blamed on the hurricane during its weeklong march across the Caribbean, 10 of them in Haiti. Marie Alta Jean-Baptiste, head of Haiti’s civil protection agency, announced Wednesday that Haiti’s confirmed death toll had doubled from five to 10.
