WARSAW (Reuters) - The United States is serious about the security of its ally Poland, Polish President Andrzej Duda said on Wednesday after meeting U.S. President Donald Trump in Warsaw.

"We see ourselves as loyal partners who cooperate on a number of issues, among others on security," Duda told a joint news conference with Trump in Warsaw's Royal Castle.

"I have a feeling that the United States is serious about Poland's security."

Poland hosts some 900 U.S. troops as part of a rotating NATO force in eastern Europe to counter potential threats from Russia.
