New questions are emerging after reports that the Flydubai attack suspect had previously been barred from flying by Oman over concerns about alleged "radical Islamic views."
The incident is raising serious questions about how security warnings are shared between countries and whether existing aviation screening measures are actually being enforced.
Passengers and crew reportedly acted quickly during the incident, with the Indian captain and Israeli passengers among those credited with helping respond.
The case is now putting renewed attention on international aviation security, background checks and how authorities handle individuals previously flagged as potential security risks.
