World leaders discuss counterterrorism efforts on the sidelines of a nuclear summit in Washington
Alongside his French counterpart, U.S. President Barack Obama says joint efforts to fight terrorism continue:
Barack Obama, U.S. President: "In the wake of the Brussels attack, with our memories of the tragedy in Paris, we have not only great urgency around the nuclear issue, but eliminating generally the scourge of terrorism. We are continuing to deepen the partnership with France around counterterrorism efforts. We've made significant strides around information sharing. President Hollande has been a leader in helping to galvanize the European community around the necessity to be more effective in transatlantic exchanges of information, and rooting out foreign fighters, identifying potential attacks, cutting off financing, and so this has been a very useful exchange in terms of examining the progress that has been made by our teams and where we where we still have to push a little bit harder."
