Italian Foreign Minister Gianfranco Fini has expressed Italy's support for the UK and its outrage over the explosions in London on Thursday morning.
In a message to his British counterpart, Jack Straw, Fini said the "barbaric terrorist attacks" had left Italians "shaken and outraged".
"I would like to express my personal solidarity, together with that of the Italian government and people," said Fini, who is also Italian deputy premier.
"Once again, inhumane terrorists have destroyed innocent lives in order to carry out their abominable plans to spread terror and death," he added.
"The tragedy further strengthens our conviction that the scourge of terrorism should be tackled at its roots, through a joint effort on the part of the international community," he said.
Fini extended his "heartfelt condolences to the families of the victims".
Meanwhile, Italian Foreign Ministry spokesman Pasquale Terracciano said that at least two Italians had been slightly injured in the explosions.
