HAVANA, Cuba - Cuba temporarily halted all mail service to the United States of packages weighing more than 453 grams (16 ounces) due to US measures to counter threats from bombs mailed from abroad, the post office said Thursday.
The measure was taken after the US Postal Service notified Cuba over "increased security measures concerning mail ... from every point of origin," the Cuban Mail Service (ECC) said in a statement printed in the local media.
Letters weighing less than 16 ounces however can still be mailed.
New rules on mailing heavier packages "will be communicated to the population at the appropriate time," the ECC said.
Direct mail between the United States and the communist island was interrupted in 1963, two years after Washington and Havana broke ties. Currently Cuban mail to the United States -- where 1.5 million people of Cuban origin live -- are routed through Mexico and Canada.
In September 2009 officials from both countries met for a first round of talks to re-establish a direct mail service.
