NYACK - A Jewish memorial service was held Tuesday in West Nyack in tribute to the three Israeli teens found murdered in the West Bank.

The service featured songs and prayers of healing for the families of Eyal Yifrach, Gilad Shaar and Naftali Frankel, who has extended family in Monsey.

The three boys went missing 18 days ago and were found murdered not far from where they disappeared. They were buried together following funeral services Tuesday.

Israeli officials say the terrorist group Hamas is behind the attack.
