Microsoft has fired four employees in response to a protest over the company’s alleged ties to Israel, with two more dismissed after a break-in at President and Vice-Chair Brad Smith’s office at the company’s Redmond headquarters in Washington state, Anadolu reports.

“Two additional employees were terminated due to serious violations of established company policies and our code of conduct,” a Microsoft spokesperson told CBS News on Thursday. The company had announced the initial two firings in relation to the event on Wednesday.

Now totaling four, the firings followed a demonstration on Tuesday by seven current and former employees at the company’s Redmond headquarters in Washington state. The activists, affiliated with the group No Azure for Apartheid, entered Smith’s office to demand that Microsoft end what they described as direct and indirect support for Israel in its war on Gaza.

The No Azure for Apartheid group identified the dismissed employees on Instagram as Riki Fameli and Anna Hattle, following their arrest by police on Tuesday.
