MOSCOW -- President Vladimir Putin on Friday signed a law banning Americans from adopting Russian children, abruptly terminating the prospects for more than 50 youngsters preparing to join new families and sparking critics to liken him to King Herod.
The move is part of a harsh response to a United States law targeting Russians deemed to be human rights violators. Although some top Russian officials including the foreign minister openly opposed the bill, Putin signed it less than 24 hours after receiving it from Parliament.
The law also calls for the closure of nongovernmental organizations receiving American funding if their activities are classified as political -- a broad definition many fear could be used to close any NGO that offends the Kremlin.
The law takes effect Jan. 1, the Kremlin said. Children's rights ombudsman Pavel Astakhov said 52 children who were in the pipeline for U.S. adoption would remain in Russia.
The ban is in response to a measure signed into law by President Barack Obama this month that calls for sanctions against Russians assessed to be human rights violators.
That stems from the case of Sergei Magnitsky, a Russian lawyer who was arrested after accusing officials of a $230 million tax fraud. He died in jail in 2009. A Russian inquiry found he was severely beaten and denied medical treatment.
The adoption ban has angered both Americans and Russians who argue it victimizes children to make a political point, cutting off a route out of frequently dismal orphanages for thousands.
"The king is Herod," popular writer Oleg Shargunov said on his Twitter account, referring to the Roman-appointed king of Judea at the time of Jesus Christ's birth, who the Bible says ordered the massacre of Jewish children to avoid being supplanted by a prophesied newborn king of the Jews.
U.S. State Department spokesman Patrick Ventrell expressed regret over Putin's action and urged Russia to "allow those children who have already met and bonded with their future parents to finish the necessary legal procedures so that they can join their families."
Vladimir Lukin, head of the Russian Human Rights Commission and a former ambassador to Washington, said he would challenge the law in the Constitutional Court.
UNICEF estimates that there are about 740,000 children not in parental custody in Russia while about 18,000 Russians are on the waiting list to adopt a child.
