Police, a bus driver, and a journalist were attacked as further violence erupted in loyalist parts of Northern Ireland last night.
A bus was hijacked and attacked with petrol bombs in Belfast, in an incident branded as "attempted murder" by First Minister Arlene Foster.
Tensions have been stretched in Northern Ireland in the past couple of years with Brexit.
But this latest spate of violence has been blamed on loyalist frustrations at the Public Prosecution Service in Northern Ireland's decision not to prosecute Sinn Fein members for attending the funeral of Bobby Storey last summer.
Taoiseach Micheal Martin's also among those calling for calm following several nights of disorder, which has left 41 police officers injured and led to 10 arrests.
An emergency debate will be held at Stormont later to discuss the ongoing violence.
