Does one who eats bread on Tishe Beav recite Nachem in Birchas Hamazon?
One who eats bread on Tishe Beav is to say Nachem in Birchas Hamazon. It is recited prior to Uvinei Yerushalayim. It is recited each time that one recites Birchas Hamazon on Tishe Beav. [However, some Poskim rule that based on Admur in the Siddur one is not to recite Nacheim in Birchas Hamazon. Practically it is to be recited. Children who ate bread are to recite Nachem in Birchas Hamazon.]
If one is not fasting, is he to wash hands as usual [until the wrist] when eating bread on Tishe Beav?
 Rama ibid; Admur 618/8 regarding Yom Kippur; Chayeh Adam 135/23
Other opinions: Some Poskim question whether Nachem is to be recited. [Elya Raba 557/3; Birkeiy Yosef 557/2; Shaareiy Teshuvah 557/1; Kaf Hachaim 557/11 concludes it is not to be said] Some Poskim rule it is only to be recited from the time of Mincha and onwards. [Ben Ish Chaiy Devarim]
