The meeting took place in the middle of the murky Rio Grande -- which divides the Mexican city Ciudad Juarez and El Paso, Texas and is crossable this time of year -- under the watchful eye of Border Patrol agents.
"It has been a very long 11 years," said Claudia Pastrana, a 42-year-old from Ciudad Juarez, after hugging her sister and niece who now live in Texas.
"It is an unforgettable moment."
More than 2,500 people of the 195 families separated by immigration or deportations attended the event, dubbed "Hugs Not Walls," which is organized by the non-profit Border Network of Human Rights group.
It is the fourth round of the event, and the second since the presidential election of Donald Trump, who has on numerous occasions targeted Mexicans with anti-immigration rhetoric.
Border patrol authorities stood on guard "so that no one is going to cross at the time of the hugs," said Ramiro Cordero, spokesman for the El Paso sector's border patrol.
After the brief but spirited meeting, Pastrana, who attended with her son and nephew, returned to the Mexican side.
From there she waved her arms in a long farewell to her sister, until she lost sight.
