Facebook says it is acquiring an Israeli mobile technology startup and opening its first office in Israel.
Facebook said in a statement on Monday that Israeli mobile utility application developer Onavo would help the social media giant create better mobile products and help connect more people around the world to the internet.
Onavo was founded three years ago and produces technology that compresses content so mobile users can use more data. The Tel Aviv-based company also has an office in California.
Israeli media reported that Facebook is buying the company for more than $US100 million ($A106.41 million) and that it was Facebook's largest acquisition of an Israeli company. Facebook declined comment.
Facebook has bought two Israeli companies in recent years, but employees were transferred to Facebook's US headquarters.
