Polish politicians have held rival observances for former President Lech Kaczynski and 95 others killed two years ago in a plane crash in Russia.
President Bronislaw Komorowski laid flowers to the victims at the Presidential Palace.
Kaczynski's twin brother and opposition party leader, Jaroslaw Kaczynski, laid a wreath at a different site at the palace.
The rival observances come as opposition supporters say the crash was not an accident and put forth assassination theories.
Meanwhile, Georgia unveiled a bust to commemorate Lech Kaczynski, a firm supporter of Tbilisi in its 2008 war with Russia.
Kaczynski's plane crashed on April 10, 2010, in Smolensk as he led a delegation to Russia to honor 22,000 Polish officers murdered by Josef Stalin's secret police at the start of World War II in the Katyn forest.
