Police detained two Argentine rights activists and several Cuban dissidents in Havana Tuesday, the organizer of an international human rights gathering said.
Antonio Gonzalez Rodiles, who was hosting the meeting at his house, said the two Argentines were supposed to attend but were detained and threatened with deportation.
On his Twitter account, Gonzalez identified the two as Pedro Robledo and Valentina Aragona.
He said five Cuban dissidents also were intercepted and detained by police before they reached his house.
An AFP journalist at the scene said police blocked vehicular access to the street where Gonzalez's house is in the Miramar section of Havana.
Separately, police detained about twenty protesters from the Ladies in White dissident group near Havana's famed Coppelia ice cream store in the Vedado neighborhood.
The Ladies in White was formed by wives and mothers of political prisoners.
