Oil rose above $69 a barrel today after Nigeria's main militant group said it attacked an oil platform belonging to Royal Dutch Shell despite an amnesty offer from President Umaru Yar'Adua.
The Movement for the Emancipation of the Niger Delta said in an emailed statement it had struck the Shell Forcados platform in the Delta state. There was no immediate independent confirmation.
The report followed an announcement on Friday by four Nigeria militant factions to accept in principle an amnesty offer from the country's president, raising hopes Africa's top oil producer would halt a battle with rebels.

Algerian Energy and Mines Minister Chakib Khelil said on Monday oil demand was still weak due to the weakness of the US and European economies and world oil stocks remained high.
Mr Khelil told reporters ahead of a meeting of gas producers an increase in OPEC oil production was hard to envisage, despite rising crude prices.
Asian stock markets slipped on Monday with Japan's Nikkei average down 1 per cent but European equities inched higher in early trade after slipping in the previous two sessions, with firmer pharmaceutical and mining stocks outpacing weaker financial shares.
US consumer confidence data on Tuesday leads a heavy calendar of economic data this week, including China's Purchasing Managers Index on Wednesday and a US jobs report and manufacturing data on Thursday.
The US data will help determine whether an oil market rally, which has lifted prices more than 50 per cent this year on hopes of economic recovery, has any legs.
