Supporters of late Polish President Lech Kaczynski scuffle with municipal guards as they try to break a barrier in front of the presidential palace in Warsaw on on August 3, 2010. Authorities failed to move a wooden cross commemorating Poland's late leader Lech Kaczynski from in front of the presidential palace after fierce protests by Roman Catholic groups and Kaczynski's followers. But supporters and relatives of the late president, including his twin brother and conservative opposition leader Jaroslaw Kaczynski, have demanded the cross remain in front of the palace as a memorial to the air crash victims.
