The Voice of the Martyrs, a group that monitors the persecution of Christians worldwide, has launched a petition campaign on behalf of a Pakistani mother convicted of blasphemy.
Asia Bibi is awaiting execution for defending her Christian faith to her Muslim co-workers.
The 45-year-old mother of five has been imprisoned for more than two years for violating Pakistan's blasphemy laws.
VOM has already gathered more than 200,000 signatures through its online Call for Mercy petition.
"The story of this petition drive is an interesting one because it started not with American Christians, but it started with Pakistani Christians," said Todd Nettleton, VOM director of media development.
The human rights group hopes to deliver 1 million signatures to the Pakistani embassy in Washington later this year.
"We don't really address the issue of the blasphemy laws. We're not attacking the Pakistani government," Nettlleton explained. "We're simply saying this Christian wife and mother deserves to be reunited with her husband and with her children."
"She doesn't deserve to be executed," he added.
VOM is also promoting Bibi's freedom by launching a video contest. To participate, entrants post a video on YouTube about Bibi's situation and the petition to free her.
The winner will receive a free trip to Washington, D.C., to help VOM deliver the signed petitions to the Pakistani embassy.
