BUCHAREST (Reuters) - Greece, embroiled in a debt crisis, remains a staunch NATO ally and will continue to observe its commitments in the alliance, NATO's Secretary-General Jens Stoltenberg said on Thursday. "Greece is a strong and engaged ally in our alliance. I am sure that Greece will continue to be so," Stoltenberg told reporters in Bucharest through a Romanian interpreter. "The Greeks underlined several times that they stand by their commitments within NATO." (Reporting by Radu Marinas; Editing by Robin Pomeroy)
