The past few days have provided a wealth of news about Iran's recent presidential election, when incumbent President Mahmoud Ahmadinejad won reelection, defeating challenger Mirhossein Mousavi. Reuters carried the post-election news:

Thousands of protesters clashed with police after President Mahmoud Ahmadinejad won an election which his reformist challenger called a "dangerous charade."

The protests were a rare direct challenge to Iranian authorities. The result and its violent aftermath raised fresh questions about the direction of Iranian policies at a time when U.S. President Barack Obama wants to improve relations with Iran.

Supreme Leader Ayatollah Ali Khamenei told Iranians to respect Ahmadinejad's victory, which upset expectations that reformist candidate Mirhossein Mousavi might win the race.

Interior Minister Sadeq Mahsouli, an Ahmadinejad ally, declared the president had been re-elected with 62.6 percent of the vote, against 33.7 percent for Mousavi.

As noted, election results were hotly protested almost immediately.  Protests continue today.
 
 
An ABCNews report, dated today, is titled "Defiant Iranian Protesters Swarm Streets of Tehran".

The rally was mostly peaceful with little police presence, although conflicting reports emerged about possible gunshots being fired. Iran's state television said shots were fired during the rally and that people were seen running away while The Associated Press said one of its photographers saw militia fire at opposition protestors, killing one.

A Mousavi supporter who was at the rally told ABC News she saw a male protester shot and injured in the leg or foot,and taken to a hosptial.

Storms of protestors shouting "Mousavi" showed up to the protest Monday despite a government ban against the rally and fears of a violent crackdown. 
The BBC reports that "thousands of Iranians have staged a rally against the re-election of President Mahmoud Ahmadinejad, defying a government ban on protests".

Following two days of unrest, the interior ministry said on Monday: "Some seditious elements had planned to hold a rally."

It added: "Any disrupter of public security would be dealt with according to the law."

Reports said paramilitaries were trying to break up the demonstration, and that students had taken cover in a mosque.

The campus has been a focus of unrest in recent days. Overnight police and militias raided dormitories, arresting dozens of students.

In related developments:

  • President Ahmadinejad reportedly cancelled a trip to Moscow, where he was due to attend a regional summit on Monday
  • Reports say Mr Mousavi's newspaper Kalameh Sabz has suspended circulation
  • About 200 relatives of detained demonstrators took part in a protest outside Tehran's Revolutionary Tribunal calling for their release, AFP reported
  • EU foreign ministers expressed "serious concern" and called for an inquiry into the conduct of the election.
Lastly, the US State Department has left unchanged it's September 15th, 2008 advisory for Americans traveling in Iran:

Some elements of the Iranian regime and the population remain hostile to the United States. As a result, American citizens may be subject to harassment or arrest while traveling or residing in Iran. In 2007, Iranian authorities prevented a number of Iranian-American citizen academics, journalists, and others who traveled to Iran for personal reasons from leaving for several months, and in some cases detained and imprisoned them on various charges, including espionage and posing a threat to national security. Americans of Iranian origin should consider the risk of being targeted by authorities before planning travel to Iran. Iranian authorities may deny dual nationals access to the United States Interests Section in Tehran, because they are considered to be solely Iranian citizens.

The Iranian regime continues to repress its minority religious and ethnic groups, including Bahai, Arabs, Kurds, Azeris, and others. Consequently, some areas within the country where these minorities reside, including the Baluchistan border area near Pakistan and Afghanistan, the Kurdish northwest of the country, and areas near the Iraqi border, remain unsafe. Armed attacks on the road between Bam and Kerman in May 2007 also render this area unsafe.

Large-scale demonstrations have taken place in various regions throughout Iran over the past several years as a result of a sometimes volatile political climate. U.S. citizens who travel to Iran despite this Travel Warning should exercise caution.

The U.S. government does not have diplomatic or consular relations with the Islamic Republic of Iran and therefore cannot provide protection or routine consular services to American citizens in Iran.
