Tough security measures remain in place
Tougher security measures remain in place around key sites in Prague as the country's intelligence services investigate the heightened treat of a terrorist attack. The government introduced the measures on Saturday night on the grounds of what it said was "the most serious threat of a terrorist attack the country had ever faced". Prague's mayor Pavel Bem told the press on Tuesday that the extraordinary measures would last for at least one week. There is speculation that the terrorist threat is linked to the arrest of four men in Norway who are suspected of planning terrorist attacks on the US and Izraeli embassies in Oslo.
