An Apache helicopter fired four missiles at a car in the Gaza Strip (searchon Tuesday, killing one person and wounding three others, Palestinian hospital officials said.

Officials at the Nasser Hospital in the southern city of Kahn Yunis said that one of the wounded was in a critical condition. They did not have the victims' identities.

The car was driving south of Khan Yunis at the time of the attack. It was not clear how many passengers were in the car, and Palestinian security sources refused to identify the car's occupants.

An Israeli army (search) spokeswoman had no immediate comment.

Israel's military has killed dozens of suspected militants and bystanders in missile strikes and other attacks during two-and-a-half years of fighting with the Palestinians.

Palestinians say the strikes amount to extra-judicial assassinations. Israel believes they're necessary to stop militant groups from dispatching scores of homicide bombers (search) who've killed hundreds throughout Israel.

Ambulances and firefighters arrived at the scene and a cloud of smoke was seen rising above the car, which had been reduced to a mass of twisted metal.

Witnesses said helicopter gunships continued to hover over the area after the attack.
