JERUSALEM — The world’s main scouting organization on Sunday said it has no connection to a Palestinian troop in Jerusalem that dedicated a recent training course to one of the killers of an Israeli-American man.

Stephen Peck, spokesman for the World Organization of the Scout Movement, said the Jerusalem troop is not a member of his organization’s Palestinian affiliate and ‘‘has no right to speak or publish on their behalf.’’

The East Jerusalem troop last month hosted a course dedicated to Baha Alyan — one of two Palestinian attackers who shot and stabbed passengers on a Jerusalem bus last October. Alyan was killed by a security guard, while a second assailant survived and is now serving multiple life sentences in an Israeli prison.

Richard Lakin, a retired school principal from Connecticut and advocate for Israeli-Palestinian coexistence, was among three people killed in the attack. Lakin’s son, Micah Lakin Avni, had appealed to the world scouting movement to expel the Palestinian Scout Association.

The Palestinians have two scouting organizations: the globally recognized Palestinian Scout Association and the Palestinian Scout and Guide Association. The Jerusalem branch belongs to the second group, Peck said.

A spokesman for the branch said its recognition of Alyan was only for his scouting activities, not politics.
