* FTSE 100 up 0.1%, FTSE 250 drops 0.4%
* Sirius Minerals sinks to record low
* HSBC and Prudential weigh on the main index
Sept 17 (Reuters) - London's FTSE 100 index inched higher
early on Tuesday as a sell-off over the implications of the
weekend attack on Saudi Arabian oil facilities eased in Europe,
while shares in UK fertilizer mining venture Sirius Minerals
tanked.
The FTSE 100 gained just over 0.1%, with heavyweight
oil majors continuing to feel the benefit of a rise in oil
prices since the attack on Saturday on the world's biggest crude
processing plant.
The midcap FTSE 250, however, fell almost 0.4%, with Sirius
Minerals diving 60% after it said it would slow
development of its polyhalite project and scrap a planned $500
million bond sale as the UK government declined to provide
support to facilitate its financing.
