Angela Merkel says she feels a duty to serve her country and Europe, adding further fuel to rampant speculation she'll seek a fourth term as German chancellor.

Merkel spoke Friday after meeting with the leaders of the United States, Spain, Italy, France and Britain.

Asked how she sees her short- and long-term responsibilities, Merkel downplayed descriptions of herself as the last great defender of Western values following Donald Trump's election.

Merkel told reporters: "One person alone can never solve everything."

Instead, she vowed to "perform my task as German chancellor, which on the one hand is to serve the people of Germany but it also includes working for the cohesion and success of Europe."

Merkel is scheduled to hold a news conference late Sunday after meeting senior members of her party.
