On Saturday the US government worked on plans to send many of the thousands of Haitian immigrants who have gathered in a Texas border city back to their Caribbean homeland. Aerial video from local media showed Haitians crossing the Rio Grande freely and in a steady stream on Friday, going back and forth between the US and Mexico through knee-deep water, with some parents carrying small children on their shoulders. People pitched tents and built shelters from giant reeds. Many bathed and washed clothing in the river.
