More security forces have been deployed in Rome following the deadly bomb attacks in Brussels, the top government official in the capital said Wednesday, warning it was impossible to predict all possible terrorist targets.
"We have increased the law enforcement presence and are assessing military contingents," said Rome's prefect Franco Gabrielli.
"We'll see what the government makes available to us," he added.
Given its size and importance, Rome has a larger security presence than other Italian cities, he said.
Gabrielli gave the example of Rome's main Termini rail station, where half a million people pass through each day, making it impractical to rely on metal detector checks to thwart attacks.
"These attackers have taught us that they strike before not after the security checks," Gabrielli said, referring to Tuesday's bombings at Brussels international airport and its metro.
Over 30 people died and hundreds were injured in the coordinated blasts claimed by the Islamic State jihadist group.
The attacks triggered security alerts across Europe.
