Nicaraguan protesters, demonstrating against the arrival of an inspection team from the international Ramsar Convention on Wetlands, cross the San Juan river by boat to reach the disputed Isla Portillos near Nicaragua's border with Costa Rica April 5, 2011. The Ramsar Convention on Wetlands and environment experts from Costa Rica were inspecting the island for environmental damage caused by Nicaragua's dredging activities. On March 8 the world court at The Hague ruled that the area was off limits to anyone but Ramsar experts accompanied by Costa Rican environment officials.
