President Bush and British Prime Minister Tony Blair have vowed to pursue the war on terrorism without compromise or hesitation.
Mr. Blair said today's (Thursday's) explosions in Turkey remind the world of the evil terrorists pose to the way of life of freedom-loving people.
He said the attacks show that supporters of democracy must stand firm and continue to fight against what he called the "fanatics of terror." He spoke at a joint news conference after talks with President Bush in London.
Mr. Bush said that the terrorists had shown their utter contempt for life and hatred of freedom. He said Britain and the United States are united in their grief and their determination to defeat terrorism.
Prime Minister Blair said their talks included such issues as weapons of mass destruction, the Middle East peace process and efforts to deal with AIDS in Africa and the Caribbean.
However, the two leaders failed to reach agreement on such issues as U-S tariffs on steel and the fate of nine British citizens held as suspected terrorist fighters at the U.S. Naval Base in Guantanamo, Cuba.
Meanwhile, tens of thousands of anti-war demonstrators marched through London to protest Mr. Bush's visit and U.S. and British involvement in Iraq. Police put the number of participants at around 70,000.
The demonstrators pulled down an effigy of Mr. Bush in Trafalgar Square, re-enacting the toppling of a Saddam Hussein statue in Baghdad during the Iraq war.
There has been unprecedented security in London for Mr. Bush's trip, which coincides with a heightened security alert because of the threat of possible terrorism.
