Seven bystanders, most of them children, were wounded in the attack.

An Israeli army spokeswoman confirmed that the military carried out the attack on a wanted member of the Islamic Jihad.

Witnesses and Palestinian security sources said the two activists, whose names were not immediately known, were travelling in the car when it exploded into a ball of flames on Monday.

Witnesses said the eight-year-old boy was killed while standing close to the car.

Two others, boys aged 14 and 15, also died, a hospital official said.

Sources said at least one rocket was fired from an Israeli occupation army aircraft into the car as it drove down Salah al-Din Street in the Gaza City centre.

An Israeli military source said one of the activists killed was involved in rocket attacks against Israel.

Hamas, which is forming a government after winning Palestinian parliamentary elections in January, called the air strike a "massacre".

Sami Abu Zuhri, a Hamas spokesman, said that "if the international community remains quiet the situation will explode."

Mahmoud Abbas, the Palestinian president, said it was a dangerous escalation against the Palestinian people.

Monday's deaths bring to 4975 the number of people killed since the outbreak of the second Palestinian uprising (intifada) in 2000.

More than three-quarters of the victims have been Palestinian.
Ehud Olmert, the acting Israeli prime minister, on Thursday lifted restrictions on the Israeli army in its operations against the Palestinian resistance movements.
