The Courant said Richard Lakin, who was principal at Hopewell School for 15 years, was on board a bus in Jerusalem when two Palestinian assailants attacked.
The two men, armed with a knife and gun, boarded the bus and killed at least one person and hurt 16 others before being stopped by police.
Lakin is in critical condition at a Jerusalem hospital after he was stabbed several times and shot. Lakin was principal at Hopewell from 1969 to 1984 before he and his family moved to Israel.
In the current wave of violence, eight Israelis have been killed in stabbing and shooting attacks. Thirty-one Palestinians have been killed, including 14 identified by Israel as attackers, and the others in clashes between stone-throwers and Israeli troops.
