CAIRO (AP) — Egyptian authorities arrested 11 Muslim Brotherhood members accused of running Facebook pages that incite violence against the police, expanding a crackdown on followers of ousted Islamist President Mohammed Morsi to include social media.

The arrests Wednesday and Thursday are a sign that after largely crippling the group in a wave of arrests and killings of protesters, security agencies are going after younger members using the Internet to keep protests alive — and looking for evidence of links to a growing insurgency and violent backlash.
