No clear winner has emerged from Israel's election, leaving a question mark over who will be prime minister, partial official results show.

Axar.az reports citing BBC.

With 63% of votes counted, the party of right-wing incumbent Benjamin Netanyahu is just behind that of his centrist main challenger, Benny Gantz.

The results indicate that both men will struggle to form a majority coalition with smaller parties.

Mr Netanyahu is hoping to stay in power for a record fifth term.

Citing sources in the Central Election Committee, Israeli media reported that Mr Gantz's Blue and White alliance was on track to win 33 of the 120 seats in the Knesset (parliament), followed by Mr Netanyahu's Likud party with 32 seats.

A centre-left bloc led by Mr Gantz and a bloc of right-wing and religious parties led by Mr Netanyahu were both projected to control 56 seats - five short of a majority.
