Thousands upon thousands descended onto our nation's capital this weekend to decry the Israel-Palestine war ... eventually hitting the White House to make their voices heard.

A massive protest formed in Washington D.C. Saturday, with upwards of a hundred thousand (if not more) pro-Palestine demonstrators marching through the streets of the city and calling for an immediate ceasefire -- while also consistently yelling "Free Palestine!"

It's one of the largest such gatherings that has taken place since the conflict kicked off last month -- and it's quite clear they don't think our government is on the right side of history here, including President Joe Biden ... whose name was front and center the whole time.

That became abundantly clear when a huge group of protesters eventually landed at the White House -- or at the front gate rather ... which keeps onlookers quite a ways away.

Still, they certainly made their presence known ... so much so, that it attracted the attention of Secret Service agents -- who came out onto the lawn and made sure nobody breached the gate and made their way onto the grounds, and by the looks of it ... no one did.

Nonetheless ... the protest at the White House got a little scary, especially when a handful of people actually scaled the gate and waved Palestinian flags ... without ever going over. There were also chants of "F*** Joe Biden" that could be heard, as well as "Allahu Akbar" ... an Arabic phrase that is the cornerstone of the Islam faith, meaning "God is most great."

The reactions to the protest are divided, and really come down to how folks feel about the Middle East conflict right now -- those who are pro-Palestine saw it as righteous and needed ... whereas others viewed it as a startling move that potentially portends worse to come.

Either way ... these people were out there making their voices heard -- and while there are reports of a smattering of arrests here and there, it looks to have remained mostly peaceful.
