The gun attack at the Al-Noor Islamic Centre left one worshiper injured. The perpetrator, who was described by law enforcement as a young white male, has been apprehended. Norwegian police are treating the case as a possible act of terrorism, assistant chief of police Rune Skjold told a news conference on Sunday.

The detained man is also suspected of killing a female relative before going to the mosque armed with three firearms and wearing body armor. The young woman was found dead at the suspect's address. The police on Sunday said the woman was identified as the stepsister of the shooter.

Several hundred people marched from the downtown Moscow's main rally site deeper into the city center, making their way to Maroseika Street and the surrounding areas - full of restaurants and clubs and within walking distance from the Kremlin - to continue their protest there, chanting anti-government slogans.

Scores of riot police in helmets and bulletproof vests arrived on site and blocked the traffic on the street.

They used loud speakers to persuade the protesters to disperse. Those who refused the appeal were arrested en masse. At least 136 were detained "for various violations," according to the Interior Ministry. Conflicting unofficial figures claimed nearly twice as many detentions were made.

Calls to go on "peaceful walks" after the Saturday rally appeared on social media in the run up to the event. Police and authorities warned that any unsanctioned marches would be immediately curbed, citing public security concerns.

A member of Sobol's team, addressing protesters from the stage at Sakharov Avenue later on, urged people to go on an unsanctioned march and was detained after finishing his speech.

Moscow has witnessed several unauthorized rallies over the past few weekends, after some opposition figures called on their followers to take to streets and storm the City Council over the disqualified candidates. Scuffles during the protests were met with a strong police response, with over 2,300 arrested. The vast majority of them were fined and set free, but some of the activists, who faced charges of provoking mass unrest and public disturbances, remain in custody.

Dear Wexner Foundation Community,

For 35 years, the work we have achieved together in this community has continued to be one of the great honors of my life, and that is why I am writing to you now.

In recent weeks, there has been considerable media attention on my past connection to Jeffrey Epstein. To be clear, I never would have imagined that a person I employed more than a decade ago could have caused so much pain. I condemn his abhorrent behavior in the strongest possible terms and am sickened by the revelations I have read over the past weeks. I sincerely value your trust, and that is why it is important you hear details and context from me directly.

I first met Mr. Epstein in the mid-1980s, through friends who vouched for and recommended him as a knowledgeable financial professional. Mr. Epstein represented that he had various well-known and respected individuals both as his financial clients and in his inner circle. Based on positive reports from several friends, and on my initial dealings with him, I believed I could trust him.

Eventually, he took over managing my personal finances. He was given power of attorney as is common in that context, and he had wide latitude to act on my behalf with respect to my personal finances while I focused on building my company and undertaking philanthropic efforts.

In the early 1990s Mr. Epstein became a trustee of The Wexner Foundation, but he had no executive responsibilities in the running of the Foundation. He did not work directly with Foundation staff, and he did not engage with leadership initiatives in any way.

As the allegations against Mr. Epstein in Florida were emerging, he vehemently denied them. But by early fall 2007, it was agreed that he should step back from the management of our personal finances. In that process, we discovered that he had misappropriated vast sums of money from me and my family. This was, frankly, a tremendous shock, even though it clearly pales in comparison to the unthinkable allegations against him now.

With his credibility and our trust in him destroyed, we immediately severed ties with him. We were able to recover some of the funds. The widely reported payments Mr. Epstein made to the charitable fund represented a portion of the returned monies. All of that money - every dollar of it - was originally Wexner family money.

I am embarrassed that, like so many others, I was deceived by Mr. Epstein. I know now that my trust in him was grossly misplaced and I deeply regret having ever crossed his path.

As the story has unfolded further, and the extent of the pain caused by Mr. Epstein continues to grow, I have spent time reflecting and searching for answers as to how this could have happened. My heart goes out to each person who has suffered unthinkable pain and I pray for their healing.

Well Wexner, an organised network of likeminded individuals would certiainly facilitate such heinous crimes to occur. The group would probably have similar predilections for chidlren and/ or a thirst for power over others, prone to using tactics such as "sextortion".

I want to convey my gratitude to the many who have written to express your trust. Abigail and I deeply appreciate your well wishes.

As I reflect on the situation, I know that we will together seek the wisdom that can be gleaned even from such troubling events. And, my friends, I want you to know that I remain fully committed to supporting your amazing and enduring leadership across the globe. Keep leading.

Les
