MILAN, Sept 28 (Reuters) - It is very unlikely that gas pipelines like Nord Stream can break down accidentally, Edison Chief Executive Nicola Monti said on Wednesday, adding that it was easy to believe the issues was caused by sabotage.

"These type of pipelines are constantly monitored to prevent corrosion so it is very unlikely that they break down accidentally," Monti said on the sidelines of a business conference in Milan. (Reporting by Francesca Landini Editing by Keith Weir)
