Oil drifted lower on Monday after Israel withdrew more soldiers from Gaza and committed to fresh talks on a potential ceasefire in the six-month conflict in the Middle East.
Brent crude futures dropped 90 cents or 1%, to $90.27 a barrel by 1000 GMT. U.S. West Texas Intermediate crude was down 86 cents, or about 0.9%, at $86.05.
Oil prices had gained about 4% last week on escalating geopolitical tensions.
Israel said on Sunday it had withdrawn more soldiers from southern Gaza, leaving only one brigade. The country has been reducing numbers in Gaza since the start of the year to relieve reservists and is under growing pressure from allies to improve the humanitarian situation.
