KABUL, Afghanistan – A court yesterday dismissed the case against an Afghan man facing possible execution for converting from Islam to Christianity, officials said, paving the way for his release.

The move eased pressure from the West but raised the dilemma of protecting Abdul Rahman after his release as Islamic clerics have called for him to be killed.

One official said freedom might come as soon as today for Mr. Rahman, who became a Christian in the 1990s while working for an aid group in neighboring Pakistan.

Muslim extremists, who have demanded death for Mr. Rahman as an apostate for rejecting Islam, warned the decision would touch off protests across this religiously conservative country. Some clerics previously vowed to incite Afghans to kill Mr. Rahman if he was let go.

Mr. Rahman was moved to Kabul’s notorious high-security Policharki prison Friday after inmates at a jail in central Kabul threatened him, Policharki’s warden, General Shahmir Amirpur, said.

Authorities have barred journalists from seeing Mr. Rahman. But yesterday, officials gave AP an exclusive tour of Policharki, which houses some 2,000 inmates, including about 350 Taliban and Al Qaeda militants.

General Amirpur said Mr. Rahman had been asking guards for a Bible but they had none to give him.

“He looks very calm. But he keeps saying he is hearing voices,” General Amirpur said.

Mr. Rahman was in solitary confinement in a tiny concrete cell next to a senior prison guard’s office. AP was shown the cell door, but barred from speaking with or otherwise communicating with him.

A senior guard said inmates and many guards had not been told of Mr. Rahman’s identity because of fears they might attack him.

But General Amirpur vouched for the prisoner’s safety. “We are watching him constantly. This is a very sensitive case so he needs high security.”

The case set off an outcry in America and other nations that helped oust the hard-line Taliban regime in late 2001 and provide aid and military support for Afghan President Hamid Karzai. President Bush and others insisted Afghanistan protect personal beliefs.

A Supreme Court spokesman, Abdul Wakil Omeri, said the case had been dismissed because of “problems with the prosecutors’ evidence.” He said several of Mr. Rahman’s relatives testified he is mentally unstable and prosecutors have to “decide if he is mentally fit to stand trial.”

Another Afghan official closely in volved with the case told The Associated Press that the court ruled there was insufficient evidence and returned the case to prosecutors for further investigation. But he said Mr. Rahman would be released in the meantime.

“The court dismissed today the case against Abdul Rahman for a lack of information and a lot of legal gaps in the case,” the official said, speaking on condition of anonymity because he was not authorized to publicly comment on the case.

“The decision about his release will be taken possibly tomorrow,” the official added. “They don’t have to keep him in jail while the attorney general is looking into the case.”

Secretary of State Rice, who said she had not received official confirmation from Afghan authorities, told Fox News the announcement was “a very good step forward.”

She said on CNN’s “Late Edition” that the American government had stressed to Mr. Karzai that religious freedom is a vital element of democracy.

“We’re going to stand firm for the principle that religious freedom and freedom of religious conscience need to be upheld, and we are hoping for a favorable resolution in this case,” Ms. Rice said.

The uproar left Mr. Karzai in an awkward position. While trying to address concerns of foreign supporters, he also has sought not to alienate religious conservatives who wield considerable influence in Afghanistan.

The court’s decision was sure to anger at least some of the clerics who have strongly demanded that authorities enforce a provision in the country’s Islamic-based laws calling for the execution of Muslims who abandon the faith.

“There will be big protests across Afghanistan,” a Sunni Muslim leader in the northern city of Kunduz, Faiez Mohammed, said. “This has shamed Afghanistan in the eyes of other Muslim countries.”

A Western diplomat, who spoke on condition of anonymity because of the sensitivity of the issue, said it wasn’t clear if the 41-year-old Rahman would be able to stay in Afghanistan or have to move abroad.

A prison official told AP that Mr. Rahman had been moved to a new prison Friday because of threats from inmates at his first jail.

Mr. Rahman was being prosecuted for converting 16 years ago while working as a medical aid worker for an international Christian group helping Afghan refugees in Pakistan. He was arrested last month after police discovered him with a Bible.

In an interview published yesterday by an Italian newspaper, Mr. Rahman said his family, including his former wife and two teenage daughters, reported him to authorities.
