HOUSTON, March 17 (Xinhua) -- Governor of the US state of Texas Greg Abbott on Wednesday criticized the federal government's policy on migrant children arriving at the border between the state and Mexico.

"The (US President Joe) Biden administration opened the floodgates to any child who wants to come across the border is going to be able to come across the border," Abbott said across the street from the Dallas convention center that is being converted into a temporary shelter for migrant children by the Federal Emergency Management Agency.

"And I know from what's going on, on the ground, they were completely ill prepared for this," Abbott added, calling the increase of unaccompanied children arriving at the Texas border a "humanitarian crisis."

Abbott also expected the number of migrants arriving at the border to increase in the short term.

"The number of children you see have come across the border already is going to be a tiny fraction of what we will see in the coming months," Abbott said. "Texas is willing to step up and help out, but this is the Biden's administration responsibility."

The governor also said that the state government would increase its efforts to investigate and apprehend the human traffickers who help migrants illegally cross the border.

Local media The Texas Tribune reported that more than 100,000 people were either apprehended by or surrendered to federal immigration officials on the US-Mexico border in February. Around one of every 10 undocumented migrants that immigration officials encountered in February was an unaccompanied minor, a 62 percent increase from January.

According to The Washington Post, the Biden administration is holding more than 4,200 teenagers and younger children in detention cells along the border designed for adults.
