Around the world, protesters have taken to the streets in solidarity in a show of international support for demonstrators facing a violent government crackdown in Iran, sparked by the death of 22-year-old Mahsa Amini in the custody of that country's morality police.

Amini was arrested on Sept. 13 in Tehran for "inappropriate attire" and died three days later in the hospital, sparking waves of protests in which more than 200 people have died, including teenage girls.

On the U.S. National Mall, thousands of women and men of all ages — donning green, white and red, the colors of the Iran flag — chanted. "Be scared. Be scared. We are one in this," some shouted, ahead of the group's march to the White House. "Say her name! Mahsa!"

The demonstrations, put together by grassroots organizers from around the United States, drew Iranians from across the Washington, D.C. ,area, with some traveling down from Toronto to join the crowd.

In Los Angeles, home to the biggest population of Iranians outside of Iran, a throng of protesters formed a slow-moving procession along blocks of a closed downtown street. They chanted for the fall of Iran's government and waved hundreds of Iranian flags that turned the horizon into an undulating wave of red, white and green.

"We want freedom," they thundered in unison.

IRAN'S ‘MORALITY POLICE’ ACCUSED OF MURDERING WOMAN FOR NOT PROPERLY WEARING HIJAB, SPARKING PROTESTS

Shooka Scharm, an attorney who was born in the U.S. after her parents fled the Iranian revolution, was wearing a T-shirt with the slogan "Women, Life, Freedom" in English and Farsi. 

In Iran "women are like a second-class citizen, and they are sick of it," Scharm said.

She said women can be arrested for wearing the wrong makeup color, historically important women are omitted from books and they have few rights in matters such as divorce and child custody. Iranian women "are standing up to unbelievable odds for basic human rights."

The Biden administration has said it condemns the brutality and repression against the citizens of Iran and that it will look for ways to impose more sanctions against the Iranian government if the violence continues.

Last month at the United Nations General Assembly, President Biden alluded to the protest over Amini's death and said the U.S. stood with the "brave women of Iran who right now are demonstrating to secure their basic rights."

In a press release on Oct. 3, Biden said the U.S. was working to make it easier for Iranians to access the internet, "including through facilitating greater access to secure, outside platforms and services." 

In Tehran, more antigovernment protests took place Saturday at several universities. The nationwide movement in Iran first focused on the country’s mandatory hijab covering for women following Amini's death on Sept. 16. The Iranian protests have since transformed into the greatest challenge to the Islamic Republic since the 2009 Green Movement over disputed elections.

In Berlin, nearly 40,000 people turned out to show solidarity for the women and activists leading the movement for the past few weeks in Iran. The protests in Germany's capital, organized by the Woman's Life Freedom Collective, began at the Victory Column in Berlin’s Tiergarten park and continued as a march through central Berlin.

Some demonstrators there said they had come from elsewhere in Germany and other European countries to show their support.

"It is so important for us to be here, to be the voice of the people of Iran, who are killed on the streets," said Shakib Lolo, who is from Iran but lives in the Netherlands. "And this is not a protest anymore, this is a revolution, in Iran. And the people of the world have to see it."

In Paris, thousands of people gathered to show their support for Iranian citizens. 

In October, Iranians, French feminist groups and politicians were among those who joined the gathering at Republique Plaza before marching through eastern Paris.

"Woman, Life, Liberty!" the crowd chanted. Some banners read: "Freedom for Iranian women," or "No to Obligatory Hijab" or "#Mahsa Amini."

Costa Rican officials have declared Gold’s Gym owner Rainer Schaller — and five other passengers who were with him — missing and presumed dead after their private plane disappeared while traveling between Mexico and Costa Rica.

According to a report published by entertainment website TMZ on Saturday, the private plane carrying the German businessman and five others — likely including his partner Christiane Schikorsky, their children, a fitness trainer, and the pilot — lost communication with a control tower somewhere near Barra del Parismina on Friday.

According to the Associated Press, Costa Rican authorities said that they have found what they believe to be pieces of the twin-engine aircraft — a nine-seat Italian Piaggio P180 Avanti — in the ocean about 17 miles off the coast on Saturday, but they have not reported finding any bodies.

“Pieces have been found that indicate that this is the aircraft. Up to now we have not found any bodies dead or alive,” Martín Arias, Costa Rica’s assistant security minister, explained in a statement.

“Around six in the afternoon we received an alert about a flight coming from Mexico to the Limon airport, carrying five German passengers,” Security Minister Jorge Torres told the press. The plane’s flight plan and manifest revealed that a 66-year-old Swiss man was flying the plane, and the passengers included Schaller (53) and four other German citizens — a 44-year-old woman, a 40-year-old man, and two minors. Torres explained that initial search efforts had begun immediately, but were later called off due to hazardous weather conditions.

Schaller is the Founder, Owner, and CEO of the RSG Group, which owns over 20 fitness and fashion brands — including Gold’s Gym and McFit — and employs 41,000 people, including franchises in 48 countries.

Costan Rican media outlet Teletica has reported that the bodies of one adult and one minor have been found within the search area, but other outlets have yet to confirm that report. Teletica also reported that, in addition to finding pieces of the plane’s wreckage, they had found luggage the believe belonged to Schaller and the other passengers.
