Nokia said it was able to transfer voice calls between a third-generation and second-generation mobile network, clearing a significant technological hurdle to the launch of the high-bandwidth 3G standard.

Greenpeace said it blocked the oil tanker Byzantio, a ship similar to the one that sank near Spain this month, from leaving the Estonian port of Tallinn with 50,000 tons of oil.

The Byzantio is chartered by the same company that contracted the vessel Prestige, which broke in two and sank off the northwest coast of Spain.
