GAZA CITY (AFP) - A Palestinian was killed in northern Gaza near the border with Israel on Monday, the DFLP group and medics said, in circumstances disputed by the Israeli army. Adham Abu Selmiya, spokesman for Gaza's emergency services, said a man had been killed by Israeli tank fire but his body was so badly disfigured that medics were not immediately able to identify him. But the Democratic Front for the Liberation of Palestine (DFLP) named the man in a statement as Ahmed Salem al-Aziza and said he had been killed by Israeli fire as he tried to place an explosive device near the border fence. The Israeli military denied any involvement in the incident.
