A12-year-old girl has shared her testimony on the conditions she faced while being held at a Texas border detention facility in the United States, saying detainees are given little food and sleep on the floor. 

The witness account comes as US Democratic lawmakers visited the same detention facility on Monday, with congresswoman Alexandria Ocasio-Cortez labelling the conditions there “horrifying” after a tour of the compound.

US President Donald Trump has targeted illegal immigration as a focus of his administration, but officials say a renewed influx of mostly Central Americans arriving at the border has strained resources.
