"Obama is restlessly heading towards war in Syria like Bush was heading towards war in Iraq. Like in Iraq, this war would be illegitimate and Obama will become Bush’s clone,” Alexei Pushkov, the head of the Russian lower house’s international committee, said on Twitter.
His remarks came after US Defense Secretary Chuck Hagel said on Sunday the White House is studying different military options against Syria.
"President Obama has asked the Defense Department to prepare options for all contingencies. We have done that and we are prepared to exercise whatever option - if he decides to employ one of those options," Reuters quoted Hagel as saying.
The unrest in Syria began in March 2011 and later escalated into a civil war. More than 100,000 people have been killed in the conflict so far, according to the UN.
Syria’s information minister said on Saturday that any US-led military action against the regime would be "no picnic.” "US military intervention will create a very serious fallout and a ball of fire that will inflame the Middle East," Syria's official SANA news agency quoted Omran Zoabi as saying.
