WASHINGTON (AP) — President Barack Obama says some foreign countries are not doing enough to confront the Ebola crisis in West Africa.

He says the international community has not been as aggressive as it needs to be to help contain what he’s calling a top national security issue for the United States.

Obama says he intends to put pressure on other foreign heads of state to “make sure that they are doing everything that they can to join us in this effort.”

He said the chances for an Ebola outbreak in the United States are low, but he says his administration is working on additional screening protocols for international airline passengers both in the U.S. and overseas.

Obama spoke Monday after meeting with his national security team.
