"It is feared that a terror cell stands behind the Sunday morning explosion near Ma'aleh Adumim and it's possible that there will be more attempts to execute terrorist attacks using explosives," a military source told The Jerusalem Post's sister publication Ma'ariv.
The source questioned the sophistication of the cell however.
"The explosive device was small and unprofessional and the terrorist was not trained," he explained.
An investigation of the incident revealed that there were gas canisters in the suspect's car that were meant to explode and cause much greater damage.
One of the reasons that the terrorist was caught was that that she was driving in the lane reserved for public transportation which led to her being pulled over by the traffic police.
She was sent to carry out the attack and the explosive was prepared for her, but the execution of the attack demonstrates that the terror cell was not organized or trained.
The source said the suspect is known to security forces and officials were checking which organization she belonged to.
"Sending terrorists with explosives looks like a Hamas operation and this is the direction of the investigation but no direction will be ruled out," he said.
The terrorist detonated an explosive and lightly wounded a police officer near the A-Zaim checkpoint on the road between Ma'aleh Adumim and Jerusalem.
The terrorist was seriously injured in the attack and was evacuated to hospital in Jerusalem with burns to her entire body, Magen David Adom said. The police officer suffered burns to his upper body and was evacuated to hospital with light injuries and in stable condition.
