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.

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

Protesters set up a “Liberated Zone” at Microsoft’s Redmond headquarters, escalating pressure on the company to end contracts with Israel.
