A handful of Twitter accounts across the UK have been suspended after it was discovered that they contain graphic images of child abuse, several British news organizations including the BBC and the Guardian report.

The London-based National Society for the Prevention of Cruelty to Children said the shocking images were revealed when hacking groups broke into private Twitter accounts. The NSPCC then received a “flurry” of reports about graphic content contained in at least six accounts -- accounts that have now been disabled.
