Thousands gather at Belfast City Hall to demonstrate their anger at the murders of two soldiers and a policeman in Northern Ireland.
Silent protests against the recent republican murders are taking place across Northern Ireland after thousands flock to a rally in Belfast.
Thousands of people have taken part in silent protests across Northern Ireland to show their anger at the murders of two soldiers and a policeman.
The peace protests happened in Lisburn, Newry, Downpatrick, Londonderry and Belfast.
A vigil is set to take place on Wednesday night in Craigavon, County Armagh, where Constable Paul Carroll was shot on Monday.
The rallies are taking place as worries grow that violence could flare up again in revenge attacks.
The republican group Continuity IRA has claimed it carried out the murder of Constable Carroll.
Another organisation, the Real IRA, says it was responsible for the deaths of sappers Mark Quinsey and Patrick Azimkar outside their barracks on Saturday.
To many young people in Northern Ireland the years of violence, bombings and killings may feel more like a history lesson than something that really happened.
"I never remembered it, I always remember it [being] on TV," said Michelle from Belfast. "I think it's quite sick kids are growing up in this world, it's sick, it's not nice."
The police are promising to bring the killers to justice, and insist the murders aren't the start of something much bigger, though.
Detectives want people who know the killers to turn them in, but in the past informers have been tortured and shot.
Two men are still being questioned in connection with the murder of Constable Carroll.
