(Updates prices, adds Kerry speech)
NEW YORK, Aug 30 (Reuters) - Brent crude oil slipped in volatile trade on Friday ahead of a long weekend in the United States as U.S. Secretary of State John Kerry confirmed plans for a "limited" strike against Syria.
In a televised address, Kerry made a broad case for limited U.S. military action against Syria for its suspected use of chemical weapons. He called Syrian President Bashar al-Assad a "thug and a murderer" and said such a "crime against humanity" could not go unpunished.
"It's clear there's going to be a military strike of some kind, but it became clear that it's going to be limited in scope and that's why we sold off," said John Kilduff, partner at Again Capital LLC.
Brent crude for October fell 90 cents to $114.26 a barrel by 1:35 p.m. EDT (1735 GMT), after earlier reaching a low of $113.63, prior to Kerry's speech.
U.S. crude for October delivery fell $1.22 to $107.58, after hitting a low of $106.75.
Oil prices were still on track for their biggest monthly gain in a year, with Brent up more than 6 percent in August, after unrest cut output in Libya by around 1 million barrels per day (bpd) and production fell in Iraq, Nigeria and elsewhere.
Traders said some selling on Friday was also linked to the long Labor Day weekend in the United States, with investors looking to close out positions ahead of the three-day weekend.
Upward momentum for prices appeared to have stalled after Britain's parliament defeated a proposal by Prime Minister David Cameron that could have led to UK involvement in an attack on Syria.
