TEHRAN, Iran -- Iran is charging three American hikers held here with espionage, a Tehran prosecutor said Monday.
The announcement came only days after U.S. Secretary of State Hillary Clinton met privately with the families of Shane Bauer, Sarah Shourd and Josh Fattal, who were detained along the Iran-Iraq border at the end of July.
Bauer, Shourd and Fattal are graduates of the University of California, Berkeley. Fatal grew up in Cottage Grove, Oregon.
Tehran's prosecutor general, Abbas Ja'afari Dolatabadi, announced the charges in an interview with the official Iranian news agency IRNA.
"The charge against the three U.S. citizens who were arrested on the Iran-Iraq border is espionage. Investigation of their cases is in progress," he told IRNA, adding: "There will be more to say (about them) soon."
Authorities in Iran had earlier charged the three with illegally entering the country, according to the semi-official Fars News Agency.
Clinton repeated Monday the Obama administration's call for the release of the hikers, requesting that the Iranian government "exercise compassion."
"We believe strongly that there is no evidence to support any charge whatsoever," said Clinton, speaking in Berlin.
"The allegation that our loved ones may have been engaged in espionage is untrue," said a statement from the hikers' families. "It is entirely at odds with the people Shane, Sarah and Josh are and with anything that Iran can have learned about them since they were detained."
White House spokesman Robert Gibbs said Monday the three hikers are "innocent young people who should be released by the Iranian government."
He said the United States has not obtained confirmation of the charges through Swiss emissaries.
Dolatabadi also said a Danish journalism student who was arrested last week in Iran is still under investigation.
"A journalist must have an official permit from authorized officials," he told IRNA. "Therefore, the investigation will continue. We have also requested information from the Ministry of Culture and Islamic Guidance (which accredits foreign journalists) and after they respond to our inquiry we will make our decision."
Dolatabadi said Iran "allowed the attorney for the Danish Embassy here today to visit" Niels Kroghsgaard, who was arrested November 4.
Danish media reported Saturday that Kroghsgaard, a journalism student from the University of Southern Denmark, had been arrested when he was at the demonstrations marking the 30th anniversary of the storming of the U.S. Embassy in Tehran.
He was in Tehran to prepare a media project for his graduation, according to the International Federation of Journalists.
The project was on the situation in Iran 30 years after the revolution, Anne Lea Landsted, administrator at the Centre for Journalism at the University of Southern Denmark, told CNN. Another student who went to Iran is now back in Denmark, she said.
"The supervisors spent a lot of time talking about security," she said, "and we didn't want them to take part in any demonstrations or things that could be dangerous."
It is unclear whether Kroghsgaard took part in the demonstrations. "All we know is that he was near the protest when he was caught," Landsted said. "His friend told him to stay away from the demonstration the last time they spoke."
She said officials at the Danish Foreign Ministry have told her they have located the prison where Kroghsgaard is being held and have been promised they will be able to visit him on Tuesday.
The two students had applied to visit Iran as students -- not as journalists, she said, as they had not yet received their degrees.
Clinton Thursday repeated a call to the Iran government to release the three American hikers on humanitarian grounds. "As a mother my heart went out to all of them. I cannot imagine what it would feel like to know that your child was in prison for now 100 days with very little contact between you and them," she said.
"I told them that we are doing everything we possibly could to get Shane and Joshua and Sarah home. And we are exploring every angle. Obviously I would hope that the government of Iran would free them on humanitarian and compassionate basis and return them to their families," she said.
The United States, which has no diplomatic relations with Iran, has relied on the Swiss to appeal directly for the hikers' release. A Swiss diplomat has met twice with the Americans in their Iranian prison.
The most recent visit was on October 29, the hikers' families said the following day.
The 40-minute visit took place at Evin Prison in Tehran, where Bauer, 27, Shourd, 31, and Fattal, 27, are being held.
"We were informed via the State Department that Shane, Sarah and Josh are in good physical shape and we're obviously happy they received another visit," the families said in a written statement. "Today marks exactly three months since our children were detained and we urge the Iranian authorities to let our children speak to us directly. Every time our telephones ring, we hope they it is them calling to tell us they've been released."
The Swiss diplomats took clothes and other supplies, including books and writing papers, to the Americans, the statement said.
State Department spokesman Ian Kelly told CNN that the Swiss ambassador was granted the second consular visit after several requests.
A senior State Department official told CNN that it was reported the three seemed to be nervous and scared, but also appeared to be in good physical and psychological health.
The Americans were detained on July 31, when, according to their families, they accidentally strayed across an unmarked border into Iran while on a hiking trip in Iraqi Kurdistan.
The only other consular access came when Swiss diplomats visited the hikers on September 29.
In an effort to obtain the hikers' release, their families in late October released video of the three -- shot two days before they were detained -- fooling around, the families said, like friends on vacation.
The video was shot by Shon Meckfessel, a friend who accompanied them on their Kurdistan trip. Meckfessel had planned to join them on the outing on which they were taken into custody but stayed behind because he felt ill.
The videos show the relaxed travelers enjoying themselves as they take a break from exploring a town in Kurdistan.
"Yo it's hot. Yo, it's hot. It's 'cause I'm in Iraq. Someone get me a fan. Someone get me a fan. 'Cause I'm in Kurdistan," Fattal raps as he chuckles and points to the Iraqi landscape behind him.
The videos have been posted on YouTube and at www.freethehikers.org.
The Americans entered northern Iraq from Turkey on July 28 during a planned five-day hike. Bauer and Shourd had been living in Damascus, Syria; Fattal was visiting. They set out to hike in northern Iraq's Kurdistan region.
Meckfessel, who spoke with Bauer via cell phone the morning of their hike, said his friends did not know they were near the border and made "a simple and regrettable mistake" by crossing into Iran.

Diplomacy is a good option. However, if that doesn't work, I suggest we propose that if they harm these innocents for no reason....we will bomb them for their crimes against humanity. Then again... we're still so busy fighting TWO wars we have no business still being in that our military isn't worth much at this point. So...we can't exactly uscle our way through things anymore.

Why would you be "hiking" along the border of 2 countries who are at war. Leave them where they are for awhile, then maybe they will appriciate the comforts of the states.
