Loyalists march

At Corner of Cathal Brugha Street I heard a man with an English accent saying that allowing them to march was "like letting the KKK march in Alabama".
March blocked at Parnell St. got the impression the Garda riot squad may be trying to force the march through.
If they do that it is certain to lead to very serious destructiion.

Barriers used during roadworks are being commandeered to create road blocks.
Several loud blasts near corner of Parnell Street, possibly fireworks (?).
Saw garda on some raised surface beside Parnell Monument being hit by flying traffic cone. Another garda standing beside him got down off barrier to assist him.
Some people retreat temporarily to Cathal Brugha Street.
Went back down O'Connell St. Overheard garda telling group of gardai to withdraw as the riot squad are handling matters. 12.52
Rudimentary block beside the spire.
Unmarked car and SUV parked on island opposite GPO.
GPO closed at one pm. Heard porter telling people "to get out of town"

I have spent too long typing this up, so the situation is likely to have changed.
Going back now to monitor "progress".
