The Name Gaara…!! (我愛羅という名…!!, Gaara to Iu Na…!!) is chapter 131 of the Naruto manga.
Gaara was horribled that he harmed Yashamaru, explaining that he didn't know who it was.

Despite his best efforts, Yashamaru had never been able to love Gaara, Gaara's existence coming at the cost of his sister's life, Gaara's mother. Since she didn't love Gaara either, Yashamaru tried to end Gaara's life by blowing himself up. Gaara survived and came to find love in proving his existence by killing others. Now intending to kill Naruto and his friends, Gaara attacks them. Naruto tries to summon Gamabunta to help him, but can only manage to summon Gamakichi.
