Iran Press/Iran : Unidentified gunmen wounded one of the demonstrators in the arm in one part of the capital, while a second was hurt while protesting elsewhere,AFP reports.
The flare-up in violence followed President Daniel Ortega's order Friday that a UN human rights mission leave the country. It had published a report criticizing the "climate of fear."

Rights groups say more than 300 people have died in the Central American nation in more than four months of violent anti-government unrest.
Sunday, scores of police and military rushed into the protest areas. Many demonstrators dropped to the ground or desperately sought cover, even scrambling up trees.
Nicaragua's unrest began on April 18 with protests against a pension reform plan, which has since been dropped.
But violent repression has led opposition anger to mushroom into a broad campaign against Ortega and his wife, Vice President Rosario Murillo, who are accused of running a corrupt dictatorship.
Protesters have demanded Ortega's resignation and early elections, but the embattled president has said he will not bring polls scheduled for 2021 forward.
