Palestinian Suicide Attacks Resume
Arafat declared a cease-fire Dec. 16 and it brought an immediate and sharp drop in violence -- no Israelis were killed by Palestinians for almost a month afterward. However, Palestinians say that Israel did not respond in kind.

From Dec. 13 to Jan. 9, no Israelis were killed in Palestinian attacks. During the same period, 33 Palestinians were killed by Israeli forces -- 22 in Israeli raids and 11 while carrying out attacks on Israeli soldiers or civilians.

When a Palestinian militant was killed on Jan. 14 in an attack that had the hallmarks of an Israeli targeted killing, Palestinian militants vowed revenge, and the suicide attacks resumed almost immediately.
