LISBON (Reuters) - Vodafone's Portuguese unit said on Tuesday a hacker attack overnight had disrupted its services but assured its customers that their personal data had not been compromised as a result of the incident, which is under investigation.

Vodafone Portugal said in a statement its system faced technical problems on Monday evening, with thousands of customers reporting they were unable to make calls or access the internet on their phones or computers.
