Federal police had stopped boarding at Terminal 1 of Frankfurt airport and evacuated part of the security area. According to German Police, a French family of four were allowed to leave the secure zone despite testing positive for explosives.

Iran Press- German police said they evacuated part of a terminal at Frankfurt Airport on Tuesday and stopped boarding due to "at least one unauthorized person in the security zone." Federal police gave the go-ahead for operations to resume about three hours after the initial security alert. Also last week passengers were cleared from the airport because of another security breach. 

A family from France was being questioned after at least one of four family members entered the secure area without having completed security checks, according to a police spokeswoman cited by Germany's DPA news agency.
