GAZA, Nov 20 (Reuters) - An explosion in the Gaza Strip killed a member of the Hamas Islamist group on Thursday, hospital staff and witnesses said. It was not immediately clear whether the man was killed by an Israeli strike or an accidental explosion. The Israeli army had no immediate comment. Gunmen from Gaza have fired dozens of rockets at Israel in the past two weeks after Israel launched raids that have killed about a dozen gunmen, and closed crossing points with Gaza, choking off some food supplies to the coastal territory.
