The authorities in Zimbabwe again cut-off internet services yesterday, four days after the start of anti-government protests that have seen at least three people killed and dozens more seriously injured.

Critics say a similar blackout earlier in the week was aimed at blocking images of the Zimbabwean security forces' heavy-handed actions during demonstrations against a spike in the price of fuel.
