Bay windows interior bricks loose. Straps?

Hi

Redecorating the front living room. Pulled skirting off and some plaster came off too. No surprise as the bricks are loose. Question is what are the straps for?

The bricks are also very loose, you can push the wall and it moves. Exterior bricks are solid.

any advice?
