Worker-led protests have erupted at Microsoft headquarters as the company promises an urgent review of the Israeli military's use of its technology in Gaza.

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.”
