JERUSALEM (REUTERS) - Israeli Prime Minister Benjamin Netanyahu on Sunday (Nov 8) congratulated US President-elect Joe Biden after his election win, saying he looked forward to working together with the new administration and strengthening the two countries' alliance.

"Congratulations @JoeBiden and @KamalaHarris. Joe, we've had a long & warm personal relationship for nearly 40 years, and I know you as a great friend of Israel. I look forward to working with both of you to further strengthen the special alliance between the US and Israel," Mr Netanyahu said on his Twitter account, which still carries a photograph of him and incumbent US President Donald Trump at its head.

"Thank you @realDonaldTrump for the friendship you have shown the state of Israel and me personally, for recognising Jerusalem and the Golan, for standing up to Iran, for the historic peace accords and for bringing the American-Israeli alliance to unprecedented heights," Mr Netanyahu tweeted.

Mr Netanyahu's message came hours after many world leaders and some Israeli ministers had congratulated Democrat Biden, even as Mr Trump refused to concede and pressed ahead with legal fights against the outcome.

The right-wing Netanyahu's particularly close ties with Mr Trump followed an acrimonious relationship with his predecessor, Mr Barack Obama, which some critics have said had alienated Democrats and compromised US bipartisan support for Israel.

Friction between Mr Netanyahu and the new administration could arise given Mr Biden's pledge to restore US involvement in the Iran nuclear deal and a likely opposition by the White House to Israeli settlement of occupied land where Palestinians seek statehood.

Having been in lockstep with Mr Trump for the past four years, Mr Netanyahu could face policy whiplash - although it may be delayed by the incoming Biden administration's need to deal first with the Covid-19 crisis and US economic woes.
