Hundreds of opponents of Nicaraguan President Daniel Ortega are in hiding in safe houses and planning their next steps to push for his resignation after Ortega loyalists, supported by police, took over a stronghold this week.

Police and armed Ortega supporters stormed the Monimbo suburb of Masaya city on Tuesday, tearing down cobblestone barricades erected during bloody protests in which at least 277 people have been killed since April.

Speaking from hideouts, leaders of the protests said they were planning demonstrations and would seek more international pressure on Ortega's government. Hundreds of protesters were in hiding, they said.
