NEWS IN BRIEF

WASHINGTON — President Barack Obama said some foreign countries are not doing enough to confront the Ebola crisis in West Africa. He said the international community has not been as aggressive as it needs to be to help contain what he called a top national security issue for the United States.

Obama said 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 said 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.

Mexico mass grave shines light on troubled state

IGUALA, Mexico — Revelations of mayhem, murder and mass graves shed light Monday on another deeply troubled region of Mexico, the southern state of Guerrero, where officials said city police in league with drug traffickers are suspected of carrying out an attack on students that left at least six dead and 43 missing.

As state officials worked to determine whether some of the missing students are among 28 bodies found in a clandestine grave, President Enrique Pena Nieto called the deaths “outrageous, painful and unacceptable.”

Pena Nieto said he dispatched federal security forces to “find out what happened and apply the full extent of the law to those responsible.”

His statement came amid rising international concern over two possible cases of mass killings involving Mexican authorities. In addition to the Iguala incident, in which 22 city police have been detained, an army unit is now under investigation and three soldiers are charged with murder in a June 30 confrontation that killed 22 suspected gang members in neighboring Mexico state.
