Microsoft employee arrested at headquarters while protesting Israel contracts

Here is a 175-word summary of the news article: Microsoft employees and community members have been protesting the company's contracts with the Israeli government at the Redmond, Washington headquarters. The protests, organized by the "No Azure for Apartheid" group, involve occupying a plaza and pouring red paint on a Microsoft sign. On the second day of protests, 18 people were arrested, including current Microsoft employee Anna Hattle and former employees Hossam Nasr and Vaniya Agrawal. The protesters are opposing Microsoft's cloud computing contracts with Israel, which they say are enabling human rights abuses against Palestinians. This comes after a recent investigation revealed Israel is using Microsoft's Azure platform to monitor Palestinian calls. Microsoft has acknowledged the new allegations and says it is conducting an independent review, while defending its human rights standards. The protests follow previous disruptions of Microsoft events by former employees accusing the company of "war profiteering" through its work with the Israeli government.
