Israeli commandos killed a senior Palestinian terrorist in the West Bank.
Special forces raided Nablus early Tuesday, killing the local Islamic Jihad leader in a shoot-out. Another Palestinian gunman, from Hamas, also died in the clash.
There were no Israeli casualties.
Hamas, which controls the Gaza Strip and last week entered an Egyptian-brokered truce with Israel in the territory, said it would not retaliate for the West bank raid.
Islamic Jihad is part of the cease-fire but has said it could break it in response to Israeli military actions in the West Bank. That faction had no immediate response to the death of its Nablus leader.
