Belum jelas siapa yang mendalangi serangan itu, namun penduduk memperkirakan gerilyawan partai oposisi Fatah, yang terlibat dalam bentrokan berdarah di jalan-jalan dengan anggota gerakan Hamas yang berkuasa, bertanggung jawab atas serangan itu karena sasarannya adalah muslim garis keras.
It was not immediately clear who was behind the attack, but residents believed that militants of the opposition Fatah party, who have engaged in bloody street clashes with the ruling, radical Islamic Hamas movement, were behind it because the targets were Islamists.
