* Berlin, Paris vow new crisis plan by end-Oct * Biggest four-day gain for Brent since August 2009 * Kuwait oil exports halt due to strike - sources (Updates prices, adds quotes) NEW YORK, Oct 10 (Reuters) - Oil rose nearly 3 percent on Monday, extending gains into a fourth straight session after a strike halted Kuwait's crude exports and France and Germany pledged to come up with a plan to tackle the euro zone crisis. German Chancellor Angela Merkel and French President Nicolas Sarkozy promised on Sunday by end-October to unveil a comprehensive new package to resolve the debt crisis, which has dragged on oil and other commodities for months. [ID:nL5E7L90RP] Optimism toward a crisis resolution has helped push up Brent more than 9 percent over the past four sessions, the biggest four-day gain since August 2009 as investors sold the dollar and put cash into equities and commodities. "There's an assumption there will be some kind of resolve in the euro zone crisis," said Richard Ilczyszyn, senior market strategist for MF Global in Chicago. "We are seeing the shorts run for the hills in the euro and all foreign currency versus the dollar. It brings up equities and the green light for commodities is on right now." Further support came after shipping sources said all oil tanker traffic from Kuwait, one of the world's top five oil exporters and a large supplier to Asia, had stopped as a customs union went on strike. [ID:nL5E7LA2LB] November Brent crude futures rose $3.00 to $108.88 a barrel by 11:59 a.m. EDT (1559 GMT), adding to gains of 4.5 percent last week, its best performance since the week to July 8. U.S. November crude gained $2.74 to $85.72 a barrel. OPEC Traders also weighed other supply factors, including word from Saudi Arabia's oil minister Ali al-Naimi over the weekend that OPEC's top exporter had cut production to 9.39 million barrels per day from 9.8 million bpd in August. But Naimi said he did not see a decline in the kingdom's exports as Libya restored production disrupted by civil war. [ID:nL5E7L90DW] The loss of Libyan oil exports, an important feedstock for European refiners, has helped push international benchmark Brent crude to a record premium to U.S. oil futures this year. The International Energy Agency said Libya may be able to return to its pre-war-level oil output earlier than 2013 if oil companies resume activities there as quickly as they seem to be doing.
