A book of condolence has been set up at the Polish embassy in Dublin to mark the deaths of Polish president Lech Kaczynski, his wife Maria Kaczynska and other top officials.
Poland's president, its central bank head and the country's military chief were among 96 people killed when their plane crashed in thick fog on its approach to a Russian airport last Saturday morning
Polish Ambassador to Ireland Tadeusz Szumowski opened the book at the embassy on Ailesbury Road in Ballsbridge.
Speaking on RTÉ's News at One, Mr Szumowski said it was too early to speculate on the causes of the plane crash.
He said was close to a number of people who died including the deputy minister for defence Stanislaw Komorowski, whose son he hosted two years ago.
“We were hosting the son of the deputy minister for defence Mr Komorowski who is a very good personal friend of ours. His wife was a schoolmate with my wife.
“We are not thinking about the political differences. We could have different opinions but this is the time we have to stay together and we are together,” he added.
Mr Szumowski said it was important for Poles to remember the past but not live in it, adding: “We truly believe that something good has to come out of this tragic event”.
The condolence book is available to sign today, tomorrow and Wednesday from 10am until 8pm.
