LONDON, June 11 (Reuters) - Northwest European gasoline refining margins on Thursday rose 23 cents to $24.95 a barrel despite higher gasoline stocks.

• Around 3,000 metric tons of Eurobob E10 gasoline barges were assessed in the Argus window.

• A further 2,000 tons of Eurobob E5 gasoline barges were exchanged, with Exxon Mobil selling to MB Energy.

• Gasoline stocks held independently in the Amsterdam-Rotterdam-Antwerp refining and storage hub rose over 10% on Thursday, data from Dutch consultancy Insights Global showed.

• Gasoline stocks rose on the week to 1.14 million metric tons and more vessels were expected over the weekend, Insights Global's Lars van Wageningen said. This was leading to longer waiting times at barges and a higher demand for light distillate vessels.

• President Donald Trump said on Thursday the United States would hit Iran "very hard tonight" and wanted at some point to take Iran's oil infrastructure hub Kharg Island, after strikes by both sides in the Gulf undermined a shaky ceasefire.
