Many Twa were also killed, despite not being directly targeted. The Tutsi RPF restarted their offensive, and took control of the country methodically, gaining control of the whole country by mid-July. The international response to the genocide was limited, with major powers reluctant to strengthen the already overstretched UN peacekeeping force. When the RPF took over, approximately two million Hutu fled to neighbouring countries, in particular Zaïre, fearing reprisals; additionally, the RPF-led army was a key belligerent in the First and Second Congo Wars.
