Authorities say possible 2nd attack planned in Barcelona

Two police officers were run over at a security point Thursday in Barcelona and received minor injuries. Early reports were unclear as to whether the incident was related to the horrible terror attack in Barcelona earlier Thursday.

Authorities found the driver of the car on the outskirts of Barcelona while a bomb disposal expert checked his vehicle.

The truck attack in Barcelona took the lives of 13 people with more than a hundred injured.

ISIS has released a statement saying that their adherents performed the attack.

"The perpetrators of the Barcelona attack are soldiers of the Islamic State and carried out the operation in response to calls for targeting coalition states," said the terror group through their news agency.

Police have arrested two men, one a Moroccan and another from Spain's north African enclave, but the driver who fled on foot is still at large and being sought by authorities.

Later Thursday police performed an operation related to the attack and there were some reports of shots fired. Authorities told people to stay in their homes while officials said they might be under a second terror attack.
