As a citizen of and believer in democracy, I applaud the efforts of Mir Hossein Mousavi. His efforts are similar to what former vice-president Al Gore should have done during the controversy surrounding the United States presidential election of 2000. Gore should have continued to protest regardless of the political risks until all the votes were counted in Florida. Instead, former president George W. Bush was appointed by the United States Supreme Court to effectively overturn the will of the people and look at what has happened to the United States in the last eight years.

Palestinian security officials in Gaza revealed on Tuesday that they thwarted an attack on former US President Jimmy Carter's convoy. Security said that they discovered two roadside bombs at the Erez border crossing, which was used by Carter's convoy to access the Gaza Strip.

Security officials added that a group affiliated with al-Qaida was behind the planned attack, and said that members of the Hamas security team were dispatched to defuse the bombs.

Islam Shahwan, a spokesman for Gaza security forces, denies that any explosives were found, and says that security arrangements for the trip went according to plan and without any breach.

On Friday, Iranian state media declared current President Mahmoud Ahmadinejad the winner of their presidential election. However, his challenger, Mihossein Mousavi is now claiming irregularities and is claiming victory as well.

According to the head of the state election commission, Ahmadinejad was leading Mousavi by 69 percent to 28 percent with just 19 percent of ballots counted.

Attempting to pre-empt any official announcements, Mousavi had earlier called a news conference during which he claimed that there had been irregularities, including a shortage of ballot papers. He declared:

"I am the definite winner of this presidential election."

Mousavi said that many people were not able to cast their ballots, even after voting had been extended by four hours.

At the news conference, Mousavi also said:

"(We) are waiting for the counting of votes to officially end and explanations of these irregularities be given. We expect to celebrate with people soon."

"We hope that authorities in charge do their work in this regard with the wisdom of the supreme leader this issue would end in a good way."

Under Iranian rules, if neither candidate can secure 50 percent of the votes, a run-off will be held on June 19 between the two front-runners.

President Barack Obama began a goodwill tour of the Muslim world, visiting King Abdullah of Saudi Arabia on Wednesday. At the same time, a new audiotape surfaced from Osama bin Laden with new threats to the U.S.

In the recording, Bin Laden said that Obama inflamed Muslim hatred towards the U.S. by ordering Pakistan to crack down on militants in Swat Valley and block Islamic law in the area. He also claimed that U.S. pressure led to a campaign of "killing, fighting, bombing and destruction" which prompted the exodus of a million Muslims in Swat Valley.

Osama's message was first broadcast on Wednesday on the Al-Jazeera Television network at almost the exact moment Obama touched down in Saudi Arabia.

Just one day earlier, Al Qaeda's #2 man dismissed Obama's trip aimed at repairing U.S. relations with the Muslim world, insisting that the overture is trumped by wars against Muslims in Iraq and Afghanistan.

In an audio message posted online, Ayman al-Zawahiri said:

"His bloody messages were received and are still being received by Muslims, and they will not be concealed by public relations campaigns or by farcical visits or elegant words."
