US President Barack Obama delivered a statement on prevention of a series of terrorist attacks. According to him, these activities were carried out jointly with the European Union.

“From the very beginning, my administration was aware that the ISIS and similar terrorist group could launch strikes,” Obama said at a press conference after G20 summit in Antalya.

 “We worked with our European partners to disrupt plots (of terrorists),” he said, adding that they succeeded in some cases. 

Unfortunately, they failed to prevent the terrorist attacks in Paris, according to Barack Obama.
