(CNN) - Sen. John McCain, R-Arizona, reiterated Thursday that the situation in Syria is growing more dire by the day, and he blasted the Obama administration for not doing enough to stop it.
"The Middle East is about to erupt," McCain said on CNN's "The Situation Room." "This is turning into a regional conflict."
The civil war has been spilling into Lebanon and Jordan and creating tension in other parts of the region, he added.
Last week the White House announced the U.S. would begin providing military support to Syrian rebel forces. McCain, who's long been an outspoken voice on the issue, suggested Syria needed all the help it can get. "It's an unfair fight," he said forcefully.
While the Obama administration has not detailed what military support it plans to give the rebels, Washington officials have told CNN that support includes arms, ammunition and, possibly, anti-tank weapons.
But McCain said that will hardly go far in helping the rebel forces fend off Bashar al-Assad's army.
"Light weapons do not do well against scud missiles and tanks, and it's just shameful," he told CNN's Jim Acosta.
