The Romanian parliament on Tuesday ratified an accord to host US missile interceptors on its soil, a day before a meeting of the 28 NATO members in Brussels.

The Senate unanimously adopted the draft law ratifying the Romania-US agreement signed in September that would allow the establishment and operation of a US land-based ballistic missile defence system in Romania as part of NATO's efforts to build a continental missile shield.

"The location of some elements of the US missile shield represents a very important contribution to the security of Romania, the US and and the entire alliance," Foreign Minister Teodor Baconschi told senators, according to Mediafax news agency.

The draft law was adopted by the lower house in November and is now set to be promulgated by President Traian Basescu.

The deployment of the missile interceptors is expected to take place in 2015 at a former airbase in southern Romania.

The missile shield, which is based on US technology, is one of the transatlantic alliance's main development axes for the coming years, NATO Secretary General Anders Fogh Rasmussen has said.

Along with Romania, Turkey, Poland and Spain have also agreed to take part in the project.
