A man carrying explosives blew himself up Sunday as participants headed to a conference between Shia and Sunni groups in southeastern Iran, killing at least 42, state-run Press TV reported.

The blast in the city of Sarbaz, in Sistan-Baluchestan, wounded 28 others, the semi-official Fars news agency said.

Among those killed were five senior officers of Iran's elite Revolutionary Guard Corps, Fars said. Read full article

(CNN) - In another move to crack down on information flowing out of Iran, the Islamic Republic's judicial chief has ordered the prosecution of individuals "who cooperate with satellite television programming providers," a reformist newspaper reported Sunday.

"The individuals, who in any way collaborate with these networks or are entrenched in the nucleus of organizations which are active through Internet sites, must be adequately and properly subject to legal actions. It is imperative that this phenomenon be seriously dealt with by all judicial authorities of the country as well as by provincial judicial authorities," Ayatollah Seyyed Mahmoud Hashemi-Shahroudi said in his order, which was quoted by the newspaper Hamshahri.

The ayatollah called on local judicial heads to work with investigators to determine "intentions, objectives and their sources of financial, political and intelligence support" of individuals who "operate against the system," according to Hamshahri, a widely circulated pro-reform publication that has been in print for more than a decade.

The scope of the reported threat and whether it was referring to international networks, reporters and stringers was not immediately clear. Because international journalists have been limited in their ability to gather news in Iran, CNN has not been able to confirm the news report.

However, the government has been trying to limit the flow of online information and other forms of communications in Iran, according to activists and human rights officials. Read full story

(CNN) - Iranians wounded during protests are being seized at hospitals by members of an Islamic militia, an Amnesty International official told CNN.

Ayatollah Ahmed Khatami says rioters in Iran will be 'firmly' dealt with if they continue to protest.

"The Basijis are waiting for them," said Banafsheh Akhlaghi, western regional director of the human rights group, referring to the government's paramilitary arm that has cracked down on protesters during the violent aftermath of the June 12 presidential election.

Amnesty International has collected accounts from people who have left Iran and expatriates with relatives there who say the Basij has prohibited medical professionals from getting identification information from wounded demonstrators who check in, Akhlaghi said on Saturday. They are also not allowed to ask how the injuries happened, and relatives are hard pressed to find the wounded.

Once the patients are treated, the militia removes them from the hospital to an undisclosed location, she said.

Iran has restricted international news agencies, including CNN, from reporting inside the Islamic republic. However, CNN has received similar accounts, including that of a woman who arrived in the United States from Iran with a broken ankle and thumb. Read full story

TEHRAN, Iran (CNN) - The Arab world is among the worldwide audience that has been closely watching as events in Iran have unfolded over the past week.

"In all honesty, I am amazed by these Iranians," Egyptian human rights activist and blogger Walid Abbas posted on his Twitter page. "I have no green t-shirt" Abbas tweeted Saturday. He was referring to the color worn by many supporters of opposition candidate Mir Hossein Moussavi, whose supposed failure to win last week's election sparked the wave of unrest that has gripped the nation.

Watching the events unfolding in Iran on Twitter, Youtube and other social networks, the Egyptian activist said he is learning from the Iranian activists. He said he does not support Moussavi because he is part of the Mullah system.

"We are not with Moussavi," Abbas tweeted, "We are with the Iranian people and their demands."

Taghlob Salah, a 24-year-old Iraqi student at Baghdad Law College, told CNN that the Iranian youths who make up most of the protesters can be inspiring to Iraqis, despite cultural differences. See images of the clashes Saturday »

"Despite the difference that we have with Iran and the fact that many Iraqis don't trust their Persian neighbor, we are still Muslims and at the end of the day that matters a lot," he said. "We will look at this phase in Iranian history and learn, for sure and I can say that we will learn from them, 100 percent."

Iraq and Iran are culturally linked because their populations are predominantly Shiite Muslims, as opposed to Sunni Muslims who make up the majority of most Arab countries. Read full story
