Turkiye  warned the Obama administration on Friday of diplomatic consequences if it doesn't quash a congressional resolution that would brand the World War I-era killing of Armenians genocide.

Foreign Minister Ahmet Davutoglu said Turkiye, a key Muslim ally of the U.S., would assess what measures it would take, adding that the issue was a matter of "honor" for his country.

"Yesterday the decision of the committee, unfortunately, has made a very negative impact from two perspectives. First of all, the judgment on historical events by parliamentary process was a big mistake. In fact the process yesterday itself showed this mistake very clearly to all of us." said Turkish Foreign Ministry.

The vote sends  the measure to the full House of Representatives, where prospects for passage are uncertain.

Meanwhile, a senior Obama administration official, speaking on condition of anonymity because of the sensitivity of the issue, said there was an understanding with the Democratic leadership in Congress that the resolution would not go to a vote on the floor of the House of Representatives.

Turkish Foreign Minister Ahmet Davutoglu accused  the Obama administration of  not putting sufficient weight behind efforts to block the vote.

Secretary of State Hillary Rodham Clinton did not answer a question about the diplomatic fallout Friday.

"The Obama administration strongly opposes the resolution that was passed by only one vote by the House committee and will work very hard to make sure it does not go to the House floor," Clinton told reporters in Guatemala City, Guatemala.

President Barack Obama had objected to the resolution, but Turkiye wants stronger action to block the resolution.

"We expect the US administration to, as of now, display more effective efforts. Otherwise the picture ahead will not be a positive one," Davutoglu told reporters. He complained of a lack of "strategic vision" in Washington.

"I declare such a decision that was taken with political concerns in mind to be an injustice to history and to the science of history," Turkish President Abdullah Gul said in the capital, Ankara.

Davutoglu said the US ambassador had been called to the Foreign Ministry for talks. The ambassador, James Jeffrey, told reporters on Friday that "we oppose the resolution."

The foreign minister said Turkey was determined to press ahead with efforts to normalize ties with Armenia but said Turkey would not be "pressured" into doing so.

He added that the vote had put the ratification of agreements to normalize ties with Armenia into jeopardy.
