Since October 1, 12 Israelis have been killed in street attacks by Palestinians, motivated in part by stepped-up Jewish visits to a Jerusalem site holy to both Muslims and Jews, and by deadlocked US-backed peace-making efforts.
Israeli forces have killed at least 73 Palestinians, including 44 who Israel says were carrying out or about to carry out attacks with knives, guns or cars. Many were teenagers.
