“We have information that a new caravan is forming in Honduras, that they’re calling ‘the mother of all caravans,’ and they are thinking it could have more than 20,000 people,” Sanchez Cordero said Wednesday.

But a WhatsApp group calling for people to gather Saturday in El Salvador to set off for Guatemala only has about 206 members.

Activist Irineo Mujica, who has accompanied several caravans in Mexico, said reports about “the mother of all caravans” were false, claiming “this is information that (U.S. Homeland Security Secretary Kirstjen) Nielsen is using to create fear.”

His group, Pueblo Sin Fronteras, said in a statement there was no evidence the new caravan would be that large, noting “there has never been a caravan of the size that Sanchez Cordero mentioned.” Indeed, past caravans hit very serious logistical hurdles at 7,000-strong.
