Facebook's plans to further integrate its various services could soon face a legal challenge.

The Federal Trade Commission is mulling whether to file an injunction against the social networking giant that could block it from its plans to stitch together its WhatsApp messaging service with the chat features of Instagram and those of its core Facebook app, The Wall Street Journal's John McKinnon and Emily Glazer reported on Thursday. The injunction could also block the company from enforcing its rules about how apps from third-party companies can work with its own services, according to the report.

Facebook's stock fell on the news. In recent trading, it was down $6.53, or about 3%, to $195.73 per share.

Before it would take effect, the proposed injunction would need to be approved by a majority of the five-person commission. The FTC would then need to file a lawsuit against Facebook and ask a court to impose the injunction as a part of that action. The agency could move forward with the plan as soon as next month, The Journal reported.

Facebook and other tech giants, including Google, Amazon, and Apple, have been under increasing scrutiny over whether they've taken actions that have curtailed competition in their respective markets. Google has already been hit with three multi-billion dollar fines by the European Union's competition regulators for stymieing rivals in areas including shopping comparison services and online advertising. Numerous Democratic presidential candidates have called for breaking up or more closely regulating Google, Facebook and other companies.

The proposed injunction could be the first step toward such a move with Facebook, The Journal reported.
