BRUSSELS, June 24 (Reuters) - The European Union will add 27 vessels to its list of sanctioned entities as part of its latest package of sanctions against Russia and they include oil and liquefied natural gas tankers, two sources familiar with the matter said on Monday.

The latest list, seen by Reuters, includes 19 energy-related vessels, including two Russian floating regasification units - the Saam and Koryak.

EU countries adopted the 14th package of sanctions against Russia earlier on Monday. The full details will be published later in the EU's Official Journal.

The list also includes ships that have been transporting defence equipment for Russia as well as the Enisey cargo ship, which the EU says has moved stolen Ukrainian grains.
