Quite odd. And suspicious. From Wanted Palestinian Turns Himself In:
Anaas Subhi Hashaash, 21, a member of the al-Aqsa Martyrs' Brigades from Nablus, was tired of playing cat and mouse with Israel Defense Forces soldiers every night and turned himself in to IDF soldiers at the Hawara checkpoint. Hashaash's family said they encouraged him to make the decision. Salah al-Jarami, a Fatah activist from Balata, said other activists, including his own brother, have been surrendering themselves recently.
