Turkey threatened Thursday to recall its ambassador Namik Tan if U.S. congressional panel votes to recognize the Armenian Genocide, a government official said on Thursday, Reuters reported.

Ankara recalled its ambassador in 2007 for consultations after a U.S. panel approved a similar bill. President Barack Obama and Turkish President Abdullah Gul held a phone conversation on Wednesday to discuss Turkey’s position on the Armenia bill.

The non-binding resolution, to be voted by the House Foreign Affairs Committee, would call on Obama to ensure U.S. policy formally refers to the massacre as “genocide” and to use that term when he delivers his annual message on the issue in April — something Obama avoided doing last year.
