MINISTER for Foreign Affairs Charlie Flanagan joined dozens of people who signed the book of condolences at the Mansion House for the students who died tragically in Berkeley this week.
Mr Flanagan said that no decisions had been made about arrangements to repatriate the bodies of the deceased.
"It is hoped that arrangements will be made shortly for the repatriation of the bodies so that they can be brought home to Ireland," he said.
"We're in close contact with everybody involved, in conjunction with the airlines."
"Obviously there is a number of families involved and the Government is assisting as much as they can in these dark and difficult times."
The Minister said he was "struck" by the number of groups and individuals who had offered assistance to the families to help bring the students home.
"What we're witnessing here this afternoon in Dublin and, indeed in other parts of the country, is an outpouring of grief on the part of the Irish people," he said.
"People everywhere feel a deep sense of sadness, grief and loss."
"These are real sad and challenging times for everyone involved," he continued.
The book of condolences is open to the public in the Mansion House on Dawson Street today until 4pm and will be open again tomorrow from 10am until 4pm.
