A Palestinian has been killed in an Israeli missile attack in the Gaza Strip, Palestinian medical sources say.
A militant group said three members came under fire as they prepared to launch a missile into Israel.
The Israeli army said the men were several metres from a fence near the Karni border crossing in northern Gaza when the air strike took place.
Initial reports said the Israelis had targeted a car in Gaza, but a BBC correspondent says this was incorrect.
A spokesman for the Palestinian Popular Resistance Committees (PRC) told a local radio station that the militants were spotted by Israeli forces and came under fire.
It is not clear whether the dead man was a militant or a bystander.
It now appears that no car was involved in the strike, the BBC's Alan Johnston reports from Gaza.
The incident comes three days before the Palestinian elections, in which Islamic militant group Hamas is challenging ruling party Fatah for the first time.
