(190918) -- TEL AVIV, Sept. 18, 2019 (Xinhua) -- Blue and White party leader Benny Gantz gives a speech during a rally with supporters in Tel Aviv, Israel, Sept. 17, 2019. Israeli Prime Minister Benjamin Netanyahu's main challenger Benny Gantz said on Wednesday morning that it is too early to declare a victory in the country's parliamentary elections and called for a unity government. Initial exit polls posted by Israel's three main TV channels showed Gantz's centrist Blue and White party had a slight lead over Netanyahu's right-wing Likud party in Tuesday's vote, hurting Netanyahu's chances of winning a record-breaking fifth term.
