CANBERRA, Australia (AP) — Australian Broadcasting Corp. has reported that four couples from the Unites States and Australia have been prevented from leaving Thailand with surrogate babies as part of a government crackdown on the burgeoning commercial surrogacy industry.

The crackdown follows recent publicity over a Thai surrogate mother who says she was left with a Down syndrome baby rejected by his Australian biological parents because of his disability.

ABC reported Friday that two Australian same-sex couples were prevented by Thai officials from leaving the Bangkok airport on Thursday with babies born to Thai women.

ABC says two U.S. couples have been prevented from leaving with babies in similar circumstances since Wednesday. The parents need court orders before they can leave with the children.

The Australian government isn’t confirming the report, citing privacy reasons.
