April 8 (Reuters) - The United States has revoked two

licenses it had granted in recent years for the development of

offshore natural gas projects between Trinidad and Tobago and

Venezuela, the Caribbean country's prime minister, Stuart Young,

said on Tuesday.

The authorizations, which have allowed Shell, BP

and Trinidad's National Gas Company to plan

the projects, now have a May 27 deadline for the companies to

wind down activities, Young said in a press conference.
