New Delhi, July 8 -- Heavy police deployments in the capitals of Kenya and Tanzania suppressed planned protests on Tuesday, with July 7 a significant date for the East African neighbors.

In Kenya, the day commemorates the 1990s struggle for multiparty democracy. In Tanzania, it marks the founding of what would become the ruling party 72 years ago.
