GAZA (Reuters) - Israel has killed a top leader of the Hamas militant group and another gunman in an airstrike on their car in Gaza, days before a key parliamentary vote on Prime Minister Ariel Sharon's Gaza pullout plan.

Medics and witnesses said a missile from an Israeli drone slammed into the vehicle on Thursday and killed Adnan al-Ghoul, a senior Hamas leader and master bombmaker for the Islamic militant group who has been on Israel's most wanted list for over a decade....

Ghoul was Hamas's top engineer who manufactured explosive devices and weapons that were used in dozens of attacks against Israelis, Palestinian sources said.

The sources said he was known as "the father of the Qassam rocket", referring to the type of rocket Gaza militants have fired frequently into Israel during the past few months. Two Israeli toddlers were killed in such a rocket strike last month.
