Three men have been charged with offences linked to protests at a university in Belfast which former US Secretary of State Hillary Clinton was attending.
There were scuffles outside Queen's University Belfast yesterday as several hundred anti-war protesters turned up to protest her presence.
Ms Clinton, who is the university's chancellor, was amongst guests at an innovation summit.
Four men were arrested during disorder as protesters tried to move through police lines towards the event.
Police have now charged three of those detained, aged 18, 20 and 21 to appear in court.
They have been charged with resisting police. The 18-year-old has also been charged with obstructing police and the 21-year-old with obstructing police and assault.
They are due to appear at Belfast Magistrates Court on 12 December.
The fourth person arrested, a man aged 57, was later released.
"The right to protest, freedom of speech and assembly are fundamental human rights," said PSNI commander Finola Dornan.
"They are protected in law and allow individuals to engage in peaceful protest, balanced against the rights and protection of others.
"What was experienced yesterday cannot be described as peaceful in nature.
"In order to manage risks to the public and to our officers, additional resources, including tactical support officers were required, significantly over and above the initial local police deployment.
"A number of our officers were injured and this is unacceptable and without justification."
She said that despite the situation police worked to facilitate people who wanted to engage in peaceful protest.
Officers are now reviewing footage with the aim of identifying any other offences.
