Latvia has begun three days of national mourning for the victims of Thursday's supermarket roof collapse which killed at least 54 people and injured dozens more.
Three of those who died in the disaster in Riga were fire officers helping people who were trapped.
The last remaining section of the collapsed roof of the supermarket caved in earlier today.
Rescue efforts have been called off until tomorrow morning because of safety concerns.
Rescuers believe hopes of finding more survivors are fading.
Investigators say the weight of soil from a garden being built on the roof of the shop may have caused it to collapse.
Rescue operations were temporally halted today as engineers and emergency teams decided on the safest method to proceed.
Around 300 square metres still need to be cleared.
The construction is fragile, however, with rescuers fearing further structural collapses.
"We have reached the most difficult phase of the rescue operation. We now have to clear the part of the building which is still covered by the roof, but the whole construction is very fragile," deputy head of the Latvian rescue and firefighting service Intars Zitans said.
"Therefore we have stopped rescue work for a while in order to decide how to act as it may collapse again," added Mr Zitans.
22 people injured in the collapse remained in hospital.
Relatives and friends of victims continue to visit the scene of the collapse, placing candles and flowers around the perimeter of the site.
Some are still waiting for information about their loved ones.
It is believed a number of people could remain trapped or are lying dead in the debris.
Book of condolences in Dublin
A book of condolence for the victims of the tragedy will be opened in the Latvian Embassy in Dublin on Monday and Tuesday.
Speaking to RTÉ News, the Latvian Ambassador to Ireland, Gints Apals, said the book will be available for members of the public to sign on both days between 1pm and 5pm.
The embassy is located at 92 St Stephen's Green.
