BUENOS AIRES, Nov. 21 (Xinhua) -- Paraguay's Defense Ministry reported a second cross-border incursion by the Brazilian troops on Friday.

    It was the second similar incident in a week after the Brazilian troops entered Paraguayan district La Paloma with tanks and other armaments, allegedly by mistake, in military exercises on Wednesday.

    Paraguayan President Fernando Lugo tried to communicate with his Brazilian counterpart Luiz Inacio Lula da Silva to ask for explanations about the troops' movements, Paraguayan daily ABC Color reported.

    Paraguayan Interior Minister Rafael Filizzolla said Friday that what occurred on Wednesday infringed Paraguay's sovereignty and the events worried and irritated the Paraguayan government.

    "The events are acts that do not contribute to the good environment that must be maintained between neighboring countries, especially those who are involved in an integration process," Filizzolla said.

    Brazil has not commented on the military events so far.
