A Christian woman who was sentenced to death in Pakistan eight years ago on blasphemy charges has been acquitted by the country’s top court.
Asia Bibi’s release was ordered by Chief Justice Mian Saqib Nisar in a landmark ruling which could ignite mass protests or violence by hardline Islamists.
Bibi had been held at an undisclosed location for security reasons and is expected to leave the country.
The charges against her date back to a hot day in 2009, when she went to get water for herself and her fellow farm workers.
Two Muslim women refused to drink from a container used by a Christian, and a few days later, a mob accused her of blasphemy. She was convicted and sentenced to death.
The mere rumour of blasphemy can ignite mob violence and lynchings in Pakistan, and combating alleged blasphemy has become a central rallying cry for hardline Islamists.
Salman Taseer, the governor of Punjab province, was shot and killed by one of his guards in 2011 for defending Bibi and criticising the misuse of the blasphemy law.
The assassin, Mumtaz Qadri, has been celebrated as a martyr by hardliners since he was hanged for the killing, with hundreds visiting a shrine set up for him near the capital, Islamabad, every day.
Ahead of the verdict, Khadim Hussain Rizvi, a hardline cleric who has brought tens of thousands of people into the streets for past rallies, called on his supporters to gather in all major cities to express their love for the prophet and to protest if Bibi was released.
Authorities have stepped up security at churches around the country.
Shortly after the ruling, hundreds of Islamists blocked a key road linking the city of Rawalpindi with Islamabad.
Islamists in Pakistan’s largest city of Karachi and in the north-western city of Peshawar were also gathering for the protests. Similar rallies were held elsewhere. Police urged demonstrators to disperse peacefully.
In the eastern city of Multan, police arrested several demonstrators after clashes.
Paramilitary troops were deployed in Islamabad to prevent protesters from reaching the Supreme Court, where security for the judges was beefed up.
Bibi’s family and her lawyer say she never insulted the prophet.
In previous hearings her lawyer, Saiful Malook, pointed to contradictions in evidence from witnesses. The two Muslim women who pressed charges denied they quarrelled with her, saying her outbursts against Islam were unprovoked.
Critics of the blasphemy law have said it is used to settle personal scores or to attack minority communities. Bibi’s case was closely followed internationally amid concern for Pakistan’s religious minorities, who have frequently come under attack by extremists in recent years.
Bibi’s husband hailed Wednesday’s verdict.
“I am very happy. My children are very happy. We are grateful to God. We are grateful to the judges for giving us justice. We knew that she is innocent,” said Ashiq Masih.
