The protest began with a prayer. Several thousand Muslims knelt in rows before the Capitol building yesterday afternoon, their knees resting on the woven rugs theyd brought from home. Women here and men over there, with onlookers to the side. Seen from the Speakers Balcony, this ranked congregation would have looked like colorful stripes spanning the grassy width of the National Mall.

We are witnessing, before our eyes, the slaughter of thousands of people on our streets, Omar Suleiman, the imam who led the prayer, had said beforehand. We are witnesses to the cruelty that has been inflicted upon our brothers and sisters in Palestine on a regular basis.

The prayer group was part of a demonstration hosted by more than a dozen self-described progressive and religious organizations to call for an Israel-Hamas cease-fire. After Hamas massacred more than 1,400 people, most of them civilians, in its October 7 attack, Israeli bombardments of Gaza have reportedly killed more than 4,000 Palestinians, the great majority of whom were also civilians.

Although the protests organizers spanned a broad spectrum of faiths and group affiliations, it appeared that most of the rally attendees were Muslim, judging by the sea of multicolored head scarves and traditional dress. But progressives of other faiths were there, too, waving the red, white, and green flag of Palestine. Rally-goers called for President Joe Biden and the United States to stop supporting Israels blockade and air assault on Gaza. (The first convoy of trucks carrying aid entered Gaza through Egypt this morning, the United Nations reported.) As I moved through the crowd, we heard speeches from Gazan expats and representatives of progressive groups such as Jewish Voice for Peace, the Movement for Black Lives, the Working Families Party, and the Center for Popular Democracy.

Enough is enough, Alpijani Hussein, a Sudanese American government employee who wore a long white tunic, told me. He and a friend carried a banner reading BIDEN GENOCIDE . Every time Hussein, a father of four, sees coverage of children killed in Gaza, he told me, he imagines his own kids wrapped in body bags. Im a father, he said. I can feel the pain.

For nearly two weeks, the world has watched, transfixed, as a litany of horrors from the Middle East has unspooled before our eyes. First, the footage from October 7: the tiny towns on the edge of the desert, bullet-riddled and burning. Parents shot, their hands tied. Women driven off on motorcycles and in trucks. The woman whose pants were drenched in blood. And approximately 200 peopleincluding toddlers, teenagers, grandparentsstolen away and still being held hostage.

Then, more death, this time in Gaza. The body of a boy, gray with ash. Rubble and rebar from collapsed concrete buildings or their ghostly shells. TikTok diaries from teenagers with phones powered by backup generators. Theyre bombing us now, the teens explain, somehow sounding calm. Almost half of Gazas population are under 18; all they have known is Hamas rulethe Islamist group took over in 2007and a series of similar conflicts. A barrage of rockets fired by Hamas and other militants; a wave of air strikes from Israel.

But this time is different: Israel has never been wounded this wayOctober 7 represented the worst attack on Jews since the Holocaustand over the protest hung a frantic sense that the vengeance had only just begun. Hackles were up and, at one point, a police car drove by, sirens blaring. Two women near me clutched each other nervously, but the officer drove on without stopping.

Inside the Capitol, a plain consensus prevailed: Many members of Congress from both parties have opposed a cease-fire and expressed strong support for the U.S. providing military aid to Israel. But outside, things werent so simple; they never are. None of the people I met said they supported Hamas, and certainly not the recent atrocities. But many said that the violence cuts both ways. Israel is a terrorist country in my eyeswhat theyve been doing to the Palestinians, Ramana Rashid, from Northern Virginia, told me. Nearby, people held placards reading ISRAEL=COLONIZERS and ZIONISM=OPPRESSION . Many protesters told me they did not believe that Israel has a right to exist. At various points in the protest, the crowd broke into the chant Palestine will be free! From the river to the sea! (Whatever that slogan might mean for protestersan anti-colonial statement or an assertion of homelandfor most Israelis it is clearly denying the Jewish states right to exist.)

A cease-fire is the minimum to save lives, a D.C. resident named Mikayla, who declined to give her last name, told me. But what we really need is an end to the occupation. Leaning against her bike, she shook her head no when I asked whether Egypt should open its doors to fleeing Palestinians. If Egypt lets Gazans leave the Gaza Strip, then that is the definition of ethnic cleansing, Mikayla said.

Other protesters I spoke with expressed concern only for ending the daily suffering of Gazans. The humanitarian crisis came first; the rest, the political stuff, would come later.

Sheeba Massood, whod come with her friend Rashid from Northern Virginia, burst into tears when I asked why shed wanted to attend. It was important to pray together, she told me. It doesnt matter if youre Muslim, if youre Palestinian, if youre a Christian, if youre Jewish, Massood said, we are all witnessing the killing of all of these children that are innocent. Everything else, she said, was politics.

When I asked the demonstrators what might happen in the region, practically, after a cease-fire was enforced, most of them demurred. Im not a politician to know all the details and technicalities of it, a Virginia man named Shoaib told me. But I think just for one horrible thing, you dont just go kill innocent kids.

Every person I met was angry with Biden. The president has been unwavering in his support for Israel since October 7, and in an Oval Office address on Thursday, he reiterated his case for requesting funds from Congress for military aid to Israel. That same day, a senior State Department official resigned over the administrations decision to keep sending weapons to Israel without humanitarian conditions.

In his remarks on Thursday, Biden spoke of the need for Americans to oppose anti-Semitism and Islamophobia equally. Fridays demonstrators, so many of whom were Muslim Americans, were not impressed with that evenhandedness.

Mr. President, you have failed the test, Osama Abu Irshaid, the executive director of American Muslims for Palestine, said from the podium outside of the Capitol. Ice-cream trucks parked nearby for tourists played jingles softly as he spoke. You broke your promise to restore Americas moral authority. Frankie Seabron, from the Black-led community group Harriets Wildest Dreams, led the crowd in chants of Shame directed at Biden. This is a battle against oppression, she said. We as Black Americans can understand! The crowd, which was beginning to thin, cheered its agreement.

As is generally the case, the program went on far too long. After two hours of speeches, the enthusiasm of an already thinned-out crowd was waning. The temperature dropped and raindrops fell, gently at first, then steadily. Finally, after organizers distributed blood-red carnations to every rally-goer, the group began the trek to the presidents house.

The demonstrators marched slowly at first up Pennsylvania Avenue, struggling with their banners in the driving rain. But as the remaining protesters got closer to the White House, the rain paused, and the sun peeked through the dark clouds. The protesters laid their flowers in the square before the White House gatesan offering and a demand for a different future for Gaza.
