Policemen scuffle with anti-North Korea and pro-U.S. activists as the police try to take away a North Korean flag (bottom) from the activists attempting to burn it during a rally to welcome U.S. President Barack Obama and to denounce the North near the U.S. embassy in Seoul November 19, 2009. Obama arrived in South Korea on Wednesday and held a summit with South Korean President Lee Myung-bak on Thursday, with North Korea and a trade deal topping the agenda of their talks. Korean characters on portraits of Obama read,'Welcome!'.
