A fresh wave of fighting erupted between Israeli forces and Palestinian militants in the Gaza Strip on Sunday, leaving an Israeli soldier and seven Palestinians dead, just as Israel and Gaza's Hamas rulers had appeared to be making progress toward ratcheting down months of border violence.
The Israeli military said in a statement: "During an IDF (Israel Defence Forces) Special Forces operational activity in the Gaza Strip, an exchange of fire evolved."
Sirens later sounded in communities across southern Israel and rockets were fired from Gaza, without causing harm.
