Mexico City, Mexico (LifeNews.com) -- Pro-life advocates in Mexico lit more than 7,000 candles on Thursday to mark the number of children killed in abortions since the Mexico City legislature legalized abortion there last year. The candles were lit in memory of the children and the women victimized by abortion.

At least one woman has already died from a legal abortion and there could be as many as eight women who have died, Jorge Serrano Limon of the National Pro-Life Committee, says.

The Legislative Assembly of Mexico City approved legal abortions one year ago today in the federal district that includes the nation's capital. Though abortion is not legal in the rest of the nation, women from across the country could go there for abortions.

They are paid for at the public health clinics the city operates and done up to 12 weeks into the pregnancy.

The Mexico Supreme Court is considering a legal challenge that could overturn the law and testimonies began in the case on April 11.

Several scientists have already told members of the high court that the unborn child is a human being with a distinct DNA from the moment of conception and that the baby's heart begins to beat before many women know they're pregnant.

Legal scholars have said the nation's constitution guarantees the right to life for unborn children and they say the new abortion law is unconstitutional.

Doctor Jorge Traslosheros Hernández testified before the court, according to ZENIT.

"If you decide in favor of indiscriminate abortion, you will be placing yourselves on the side of those who throughout history have held back the rights of Indians, women, black people, Jews, and now too, the embryo," he said.
