Story highlights The injured included the toddler's parents and brother, authorities say

The baby killed was about 18 months old

(CNN) A Palestinian's home was burned during a "price tag" attack Friday that killed a toddler and critically injured at least three other relatives, Israeli and Palestinian officials said.

The injured were the toddler's parents and a brother, said Ghassan Douglass, a Palestinian official in charge of settlement activity north of the West Bank, where the attack occurred.

The boy who died, Ali Saad Dawabsha, was about 18 months old, Douglass said.

Authorities found the words "price tag" on the walls of the house in Duma, said Luba Samri, a spokeswoman for Israeli police.

A "price tag" attack is a term used by radical Israeli settlers to denote reprisal against Palestinians in response to moves by the Israeli government to evacuate illegal West Bank outposts, according to officials.
