President Donald Trump's order to stop separating migrant children from their parents spread confusion and uncertainty along the border, with no clear plan to reunite families but with growing signs the administration is dialing back its "zero tolerance" policy on those entering the U.S. illegally.
Immigrants who remained locked up and separated from their families struggled to get in touch with children being held in many cases hundreds of miles away.
Some parents said they didn't even know where their children were.
A senior Trump administration official said that about 500 of the more than 2,300 children taken from their families at the border in recent weeks have been reunited since May. Federal agencies are working to set up a centralised reunification process for the remaining children at a detention center.
