Israeli defence chiefs have put curbs on social networking sites such as facebook after the officials discovered some soldiers had uploaded pictures of themselves with classified equipment, inadvertently revealing sensitive information. A review of Facebook pages belonging to Israeli troops found that some had posted detailed pictures of air bases, operations rooms and inside submarines.

A new list of rules announced Thursday aims to prevent soldiers and Defense Ministry employees from revealing classified information on social networking sites.

The new set of rules - which have not been made public and some of which existed previously - include a ban on images of pilots and members of special units, and anything that shows specific military manoeuvres.
