Mexican police suspect drug gangs caused the attacks in Acapulco, Mexico, in which at least 35 Americans have been killed, said Matthew Chambers of the U.S. Department of Homeland Security around 12:10 p.m. Pacific time.
However, Chambers said, police have almost completely ruled out the Zetas.
“They seem to think they are the least likely suspects,” Chambers said.
The DHS is still unsure of the attacks in Mexico are related to ones in Las Vegas that occurred at about the same time Friday.
Chambers said there is not evidence yet to point to drug gangs or al-Qaeda in the Las Vegas attacks. However, he said, officials are looking at all possible options and are not ruling anybody out.
Also, Chambers said, the DHS is now saying it cannot confirm the number of casualties it reported earlier. He said he doesn’t know who reported 200 people had died in Las Vegas, nor did he know where Mexico National got its number of 500 deaths. Those numbers are “speculative,” he said.
“We don’t have any concrete numbers right now,” Chambers said.
