WASHINGTON, Aug 28 (Reuters) - Microsoft (MSFT.O)

Microsoft has fired four employees who participated in protests on company premises against the firm's ties to Israel as it wages war in Gaza, including two who took part in a sit-in this week at the office of the company's president.

Anna Hattle and Riki Fameli received voicemails informing them that they were fired, the protest group No Azure for Apartheid said in a statement on Wednesday.
