A major garda operation is underway at St Patrick's Cathedral where 41 Afghan asylum seekers have been on hunger strike since Sunday.
It had been reported earlier that gardaí had entered the building but sources inside are now disputing this.
At least 30 gardaí are stationed around the cathedral, and at least five garda vans are parked outside the gates.
It is thought the gardaí may be trying to remove the seven minors among the protestors and place them in the care of the HSE.
It is understood that the HSE obtained an order from the High Court to remove the juveniles this morning.
