Italian police say they are making arrests of suspected members of an Islamic terror ring which allegedly helped execute attacks in Pakistan, including the market bombing that killed more than 100 people.

Anti-terrorism police in Sardinia said Friday they were executing arrest warrants for 18 suspects. Police said some of the suspects were responsible for "numerous bloody acts of terrorism in Pakistan," including the October 2009 explosion in a market in Peshawar in which more than 100 people died.

Police said the aim of the terror network was to create an insurrection against the Pakistani government.
