Trump blasts Obama as 'respectful' transition of power in US evaporates
US President-elect Donald Trump has accused Barack Obama of creating "inflammatory" roadblocks as he leaves office.
The tycoon also claimed the outgoing administration treated Israel with "total disdain", further straining the veneer of civility between the incoming and outgoing leaders.
Although Mr Trump did not flesh out his complaints in a series of broadsides posted on Twitter, he made it clear that Mr Obama's recent claim that he would have won the election had he been running did not sit well with him.
Previously, Mr Trump was largely respectful about the current US President (right), but that evaporated in a series of attacks.
He tweeted: "Doing my best to disregard the many inflammatory President O statements and roadblocks.
"Thought it was going to be a smooth transition - NOT!"
Mr Trump also took direct issue with the Obama administration's decision to let a UN Security Council resolution critical of Israel pass.
"We cannot continue to let Israel be treated with such total disdain and disrespect," he said in a two-part tweet. "They used to have a great friend in the US, but... not anymore. The beginning of the end was the horrible Iran deal, and now this (the UN resolution)!
"Stay strong Israel, January 20th is fast approaching!"
The incoming leader also took aim at Mr Obama for claiming that had he run again, he would have been victorious.
Mr Trump's response to that was: "NO WAY!"
Mr Trump and his team have until now been largely complimentary about the way Barack Obama and his administration have handled the transition of power.
The US President-elect's complaints about the treatment of Israel came a few hours before John Kerry was due to make his final speech about peace in the Middle East as Secretary of State - remarks some Israeli officials panned in advance.
The administration's decision not to veto the critical UN resolution further aggravated the already strained US-Israel relationship.
