Polish President Lech Kaczynski, who was killed in a plane crash in Russia over the weekend, will be buried alongside his wife on Saturday, Polish state television reported Monday.
The body may be put on display at the Presidential Palace for the public to pay respects starting on Tuesday, TVP Polonia reported.
Poland was shocked over the weekend by the crash, which killed dozens of political, military, economic and civic leaders along with Kaczynski.
Only 14 bodies - out of nearly 100 killed - have been positively identified, according to Jacek Sasin, and official in the Chancellery of the President's Office, Polonia reported.
Kaczynski's body returned to tributes in his homeland Sunday afternoon.
Soldiers in perfect step carried the casket from the plane onto the tarmac, where mourners were waiting. Catholic priests recited prayers at the military airport before Kaczynski's daughter and twin brother, followed by others, took turns kneeling before the flag-draped casket.
The Kaczynski family will decide where the late president and his wife will be laid to rest, Sasin said.
Tens of thousands of Poles across the country observed a two-minute moment of silence Sunday to remember their president and others killed in the plane crash.
Meanwhile, investigators said they found the aircraft's flight data recorders in good condition and began deciphering them Sunday, the independent Russian Interfax News Agency reported.
Residents flocked to central Warsaw, the site of the presidential palace, to mourn Kaczynski. They left wreaths and lit candles. By Sunday, the numbers grew to about 100,000 by some estimates. Many cried openly. Others stared blankly at the sky.
On Monday, the country begins a week-long period of mourning.
The plane carrying Kaczynski crashed Saturday morning while trying to land at an airport near Smolensk in Russia.
