Global oil prices fell on Tuesday as traders took profit after a long holiday weekend, and Ukraine's new president launched a fresh offensive against rebel groups, giving traders an impression of stability in spite of renewed violence.
Analysts expect any price weakening to be brief as Libyan oil exports fell further and conflict in the eastern Ukrainian city of Donetsk could raise the risk premium.

In Libya, new protests slowed work at Hariga port as the OPEC producer's output fell to 160,000 barrels per day (bpd), far less than the 1.4 million bpd produced before the 2011 uprising against Muammar Gaddafi.
Meanwhile, Ukrainian forces fought separatists in Donetsk for a second day on Tuesday after inflicting heavy losses on the pro-Russian rebels. The rebels had occupied strategic points in Donetsk and other towns in the east shortly after Sunday's presidential election. The election victor, Petro Poroshenko, rejected any talks with "terrorists."
