Sea Shepherd to stop intercepting Japanese whaling vessels

Anti-whaling group Sea Shepherd has announced it will not intercept Japanese vessels in the Southern Ocean this season.
The anti-whaling group's ships have confronted ships off Antarctica each year since 2005.
Sea Shepherd founder Captain Paul Watson said the group could no longer match Japan's surveillance technology.
He accused nations including Australia, New Zealand and the US of being "in league" with Japan.
"Japan is now employing military surveillance to watch Sea Shepherd ship movements in real time by satellite and if they know where our ships are at any given moment, they can easily avoid us," Mr Watson said in a statement.
He told the Australian Broadcasting Corp: "We do not have their money, we do not have their technology. We are going to have to find an alternative way to deal with them and we will."
Mr Watson did not detail potential future tactics.
Why is Japan still whaling?
The legalities of hunting whales
Despite an international moratorium on whaling since 1985, Japan's fleet sails to the Antarctic in the autumn or winter each year, returning the following spring.
