Hungarian police have fired tear gas, after hundreds of migrants broke through a razor wire fence on the border with Serbia.
A pregnant woman was seen being stretchered from the scene, and footage later emerged of weeping children who had been sprayed in the clashes.
A number of children have been injured.
Syrian mother Rasha, one of those stranded in Horgos, says parents are trying to make sure their children are safe: "We have to pass, if they don't want to take us take our kids, okay, take my kid and put her in Germany or any other safe place."
"I want to go for my kid, all of them want to go for their kids not for themselves."
