The Nauru Government says it has activated off-duty police to secure the tiny Pacific island against the threat of further protests.
The Government accused Opposition MPs of trying to destabilise it by spreading "lies and mistruths" through foreign media, and of trying to score political points over Tuesday's protest outside Parliament.
Numerous police officers were admitted to hospital and two were left with chest injuries, while some of the building's windows were smashed, the Government said.
"It was a blatant criminal act in which 10 police officers were hurt and needed medical treatment," a statement said yesterday.
