She is looking forward to joining her sons in paradise.
The article says that she did not cry for more than five minutes upon news of her son Ahmad's death on Saturday.
She expressed joy and praised Allah for what happened, and expressed hope that her sons are all accepted into Paradise where they would be, presumably, happily screwing a bunch of virgins for eternity.
Khalil also expressed her fervent wish that Islamic Jihad continue to create Jewish widows and orphans. She called on Allah to grant success to the "resistance" and to defeat the Jews for "our land."
She has two more sons left, as well as two daughters. Ahmed also leaves behind three wives.
One of Ahmad's remaining brothers said "we always expected him to be killed."
You see? Terrorist families are just like everyone else. You just have to understand their culture, and show empathy for them.
