In Rome today, a parcel bomb exploded at the Swiss embassy, seriously injuring an embassy employee, and hours later, a parcel bomb exploded at the Chilean embassy, slightly injuring an employee there. No group has claimed responsibility for the bombings. Authorities are looking into possible links with a rash of mail bombings in November at foreign embassies in Athens by suspected anarchists.
