Microsoft Corp. activist employees and supporters were arrested after returning to the company’s headquarters for a second day to demand that the software maker sever business ties with the Israeli military.

The protesters set up tents in a “liberated zone” on the Redmond campus and toted signs that urged co-workers to “Join the worker intifada: no labor for genocide.”

Police officers arrested 18 people at worker-led protests at Microsoft headquarters Wednesday as the tech company promises an “urgent” review of the Israeli military's use of its technology during the ongoing war in Gaza.
