Tel Aviv (dpa) - Palestinian militants in the Gaza Strip fired a rocket at Israel again in the evening. The missile intercepted the missile, Israel's army said. Warning sirens howled in Israeli border towns and the coastal city of Ashkelon. There, the attack interrupted an election campaign event by Prime Minister Benjamin Netanyahu. It is the second such incident since September. Netanyahu's right-wing conservative Likud will elect a new leader tomorrow, who will then lead the party to the new election in March. Netanyahu's re-election is considered likely.
