Asia Bibi meeting Pope Francis during an appeal of earlier death sentence.
Pakistan's Supreme Court has acquitted a Christian woman who has been on death row for almost eight years on blasphemy charges.
Asia Bibi, a mother of five from Punjab province, was convicted of blasphemy in 2010 and sentenced to hang after she was accused of defiling the name of the Prophet Muhammed during an argument the year before with Muslim colleagues.
The workers had refused to drink from a bucket of water Asia Bibi had touched because she was not Muslim.
At the time, Asia Bibi said the case was a matter of women who didn't like her "taking revenge."
She won her appeal against the conviction and subsequent death sentence on Wednesday.
David Curry, CEO of Open Doors USA, an organisation that lobbies on behalf of Christian minorities, said in a statement that "we are breathing a sigh of relief today."
"These charges stemmed from her Christian identity as well as false accusations against her," he said.

"We are hopeful that Pakistan will now take additional steps to offer religious freedom and basic human rights throughout the country."
Under the Pakistan penal code, the offence of blasphemy is punishable by death or life imprisonment.
Supporters of Pakistani radical religious Tehreek-e-Labbaik party protest against Christian woman Asia Bibi in Lahore, earlier this month.
Widely criticised by international human rights groups, the law has been used disproportionately against minority religious groups in the country and to go after journalist critical of the Pakistani religious establishment.
Her case has attracted widespread outrage and support from Christians worldwide, and condemnation from conservative Islamist groups in Pakistan, who have demanded the death penalty be carried out and threatened widespread protests in the event of her being freed.
Islamist movement Tehreek-e Labbaik had previously vowed to take to the streets if Bibi was released.
The case has been extremely divisive within Pakistani society, splitting liberals and conservatives and leaving even many supporters afraid to speak out on Asia Bibi's behalf.
In 2011, senior politician Salman Taseer was shot dead by his own bodyguard for voicing support for Asia Bibi and condemning the country's stringent blasphemy laws.
His killer, Mumtaz Qadri, immediately surrendered to police and was later executed, becoming a martyr for many hardline Islamists.
Qadri's grave, in the capital city of Islamabad, has since become a shrine for those supporting Asia Bibi's death sentence.
