(Reuters) - U.S. package delivery service UPS has re-established shipping to the bulk of Puerto Rico's postal areas, the company said on Thursday, although power outages and blocked roads continue to hamper deliveries.


"We are pleased to begin operations again in Puerto Rico, though the situation is dynamic," UPS Americas Region President Romaine Seguin said in a statement.


The company said freight services were now available to 149 of the island's 176 zip codes and added it would offer a hurricane aid discount to individual customers.
