How to best attack these weeds (back yard rowhouse patio in Washington, DC)

Hey all -

This is the 2nd summer we've been at this rowhouse on capitol hill in DC with a small backyard.

For some reason, far more weeds between these pavers.

So many more that I don't recall doing any weeding last year at all, and with no treatment at all or work done yet, it's like a little green forest out there.

What is the best way to attack these so that they're gone, and don't come back...at least for a few months.

Some photos attached:





Thanks for y'all's help in advance.
