Rome is packed with police ahead of US president George W Bush's visit. The American leader arrives late tonight, and some 10,000 extra police officers and troops have been drafted into the Italian capital to make security airtight. The US embassy has all its approaches tightly controlled. The Italian communist party, anticipating an airspace ban later today, has already taken wing with a banner protest in the Roman skies. However, the Italian government is determined to ground them and anyone else who will make waves during the Bush visit. One young man said he and his friends will disrupt the visit by exercising their rights as citizens, as Romans have for the past year refused the war in Iraq, and they will refuse a war leader. Posters against Bush, America, and the visit are much in evidence, but Rome's prefect and police chief Achille Serra is serene. He says that while his men are expecting demonstrators from all over the country, the police will not be creating a situation of tension and there will be no repeat of the violence seen at the 2001 G8 summit in Genoa. No areas will be blocked, and peaceful protest will be allowed. Captors in Iraq holding three Italians have released a new video of the trio, and have called for Italians to protest in Rome to coincide with the visit. The hostages continue to appear in good health. A fourth man was executed in April. **PHOTO CAPTION*** Captors in Iraq holding three Italians have released a new video of the trio, and have called for Italians to protest in Rome to coincide with the visit.
