US IT company Apple has announced the suspension of the social networking app Parler, saying the service had not taken adequate measures to prevent the spread of posts inciting violence.
Apple said in a statement, "We have always supported diverse points of view being represented in the App Store, but there is no place on our platform for threats of violence and illegal activity."
It also said, "Parler has not taken adequate measures to address the proliferation of these threats to people's safety. We have suspended Parler from the App Store until they resolve these issues."
Major IT firm Google has also suspended the distribution of Parler apps, citing its imminent threat to society.
The company says that app users continued to post messages inciting violent acts.
Local media say Parler is used by many conservatives, including supporters of President Donald Trump.
They say messages were also exchanged via the social network regarding Wednesday's storming of the Capitol in Washington. The incident left five people dead.
