Azerbaijani Foreign Ministry spokesman Elman Abdullayev told journalists on November 14 that a protest note will be handed to Uruguay's foreign minister soon.
He said that "these kinds of visits undermine the peaceful resolution of the Nagorno-Karabakh conflict and might lead to very bitter consequences for Armenia."
A delegation headed by Jorge Orrico, chairman of Uruguay's House of Representatives, visited Nagorno-Karabakh and held talks with the region's Armenian separatist leaders on November 13.
Armenia and Azerbaijan have been in conflict for more than two decades over Nagorno-Karabakh, which has a majority Armenian population. A fragile cease-fire has been in place since 1994.
