Dozens of pro-Palestine protesters gathered in the city to mourn lives lost in the conflict in Gaza.
The event in New Road this afternoon was organised by Brighton and Hove Ceasefire Coalition, who were coming together "to grieve the loss of life and tell our politicians to call for a ceasefire now".
Some held Palestine flags and signs including one which read "an eye for an eye will make us all blind".
The sit-in began with music, followed by a spokeswoman who talked to the dozens gathered in front of the Theatre Royal.

She said: "As we reach a point of fatigue and despair, we are coming together for those being denied basic human rights.
"I hope that today can be an act of collective empathy, an act of collective grief."
Officers from Sussex Police were keeping an eye on the event but have not yet interacted with protesters.
It comes after a national day of action on Saturday, with thousands of people taking part in events around the UK.
On previous weekends thousands of protesters and counter-protesters have converged on London, including members of Brighton and Hove's Palestine Solidarity Campaign who attended the large rally last weekend.
