BRUSSELS (Reuters) - European Union governments imposed sanctions on Tuesday against major Iranian state companies in the oil and gas industry, and strengthened restrictions on the central bank, cranking up pressure over Tehran's nuclear program.
Among the more than 30 companies and institutions targeted were: the National Iranian Oil Company and its subsidiaries, and the National Iranian Gas Company and others, overseeing oil refining and distribution and transport of oil.
The ministries of energy and petroleum were also included.
