U.S. Senator Jeanne Shaheen has demanded an independent international investigation into Tanzania's post-election crackdown following a CNN exposé uncovering evidence of shootings, mass graves, and potential cover-ups by security forces.

• Ranking Member of the U.S. Senate Foreign Relations Committee Jeanne Shaheen condemned the "disturbing actions" by Tanzanian authorities after the October 29 presidential election.
• The CNN investigation utilized satellite imagery, geo-located videos, eyewitness accounts, and forensic audio analysis to document alleged police killings and secret burials.
• Tanzanian President Samia Suluhu Hassan won with 98 per cent of the vote; she has announced a national commission of inquiry, but critics urge an independent body.
• The United Nations Human Rights Office estimates hundreds may have been killed, with many more injured or detained during the unrest.
• The Tanzanian government has criticized CNN for "unverified" and biased reporting, accusing journalists of not seeking their comment.
