A pro-Palestine rally failed to attract protesters at the Colorado state Capitol on Friday, even as tens of thousands took to the streets across the Middle East and other parts of the world amid the Israel-Hamas war.

A former Hamas chief had earlier called for protests across the Muslim world in support of Palestinians and urged people of neighboring countries to join the fight against Israel.

In Denver, the state Capitol was quiet.

Meanwhile, a pro-Israel rally is also planned at the state Capitol on Sunday.

Communities across America have beefed security measures after the Hamas terrorist group attacked Israel on Saturday, killing around 1,300 people as of Thursday. The initial attack is believed to be the largest number of Jewish people murdered in a single day since the Holocaust. Retaliatory strikes from Israel have killed around 1,900 in Palestine.

In Denver, the police said they bolstered security around high-profile places in the Jewish community.

“The Denver Police Department has been providing extra patrols around synagogues and mosques since Saturday and have been in contact with representatives from both the Jewish and Muslim communities to learn about any specific safety concerns that may arise,” the police said.

Police said officials have not identified “any specific threats in Denver.” The Biden administration also said there is no specific or credible threat to the homeland but encouraged the public to nonetheless “stay vigilant and stay informed.”

“As always, we ask the public to remain vigilant. If they observe any suspicious or illegal behaviors, they are encouraged to immediately report it to police,” the Denver police said.

Dan Leshem, director of the Jewish Community Relations Council at JEWISHcolorado, said it has been a “very traumatizing and anxiety-inducing week.”

He said the Jewish community should not panic but remain vigilant and careful.

“To a certain extent, there’s a baseline level of anxiety and threat that every Jewish American feels every day of their lives,” he said. “It’s heightened by what’s going on in Israel because, if you look historically, these are always times of rapid increases of threats and attacks against the Jewish community — both online and in-person.”

Leshem encouraged the Jewish community to use resources provided by organizations, such as JEWISHcolorado, a nonprofit organization that works as an umbrella for Jewish organizations in the state. The group partners with the Secure Community Network, a nationwide security organization that works with the FBI to monitor potential threats.

Leshem said that Secure Community Network also hasn’t detected any credible threat to the Jewish communities in America.

Police departments in major U.S. cities have bolstered forces for the upcoming weekend.

In New York, the police there planned for “enhanced protective deployments out of an abundance of caution at large gatherings, cultural sites and houses of worship among other locations to ensure public safety and security.”

In Florida, Gov. Ron DeSantis declared a state of emergency, allowing local officials to increase law enforcement around school campuses and protests.
