Alexandra Kinova has given birth to quintuplets in the Czech Republic, officials say, a first for the country.
Alexandra Kinova, 23, had four boys and a girl by caesarean section on Sunday, they say.
The births took place “without any complications”, according to doctors at Prague’s Institute for the Care of Mother and Child.
The mother and babies were placed in an intensive care unit but are believed to be in a good condition.

The Czech Republic’s first quintuplets, who were conceived naturally without IVF, have a 95% chance of growing up healthy, the Associated Press quoted Zbynek Stranak, chief doctor at the neonatal section of the institute, as saying.
The boys’ names are reportedly Deniel, Michael, Alex and Martin, while the girl is called Terezka.
Alexandra Kinova, who is from the town of Milovice, about 12 miles north-east of the capital, Prague, already had one son.
She originally believed she was pregnant with twins, but in March doctors upped it to four – and then five in April.
The father of the quintuplets was present at the delivery despite his train being delayed, according to the newspaper Ceske Noviny.
“I was crying all the way since I feared I would not manage it,” he said.
The odds of naturally conceiving quintuplets are one in several million, according to Dr. Wright Bates, from the University of Alabama.
Dr. Wright Bates told ABC News that quins are “exceedingly rare”.
He said twins are born in up to 1 in every 100 births, while triplets are 1 in every 7,000 to 10,000 births.
Naturally conceived quadruplets are born in every 1 in 600,000 births.

The first recorded set of quintuplets known to have all survived were the Dionne sisters, who were born in Ontario, Canada.
Fewer than 10 sets of quintuplets are born every year in the United States.
Last month, Guillermina and Fernando Garcia had five babies – three girls and two boys – who weighed between 2 to 3 pounds each at the University of Utah hospital in Salt Lake City for another six weeks.
In 2010, British mother Vicky Lamb had four girls and two boys after taking a fertility drug but sadly one of the babies died.
