Bolivian President Evo Morales says he will not agree to a U.S. request to return weapons and equipment in an ongoing disagreement over the naming of a new commander for Bolivia's counterterrorism unit.

Mr. Morales responded Tuesday to a written request by the U.S. Embassy that objected to the new unit commander. Mr. Morales has called the U.S. request blackmail.

U.S. officials have confirmed that Washington will cancel its counterterrorism programs in Bolivia after its decision last week to drop the country from its list of anti-terrorism partners.
