An ‘armed and dangerous’ Ukrainian woman is suspected of setting off the bomb in the centre of Monaco.

Interpol is working to create a Most Wanted red notice for the 30-something attacker after issuing an arrest warrant.

She is said to have targeted billionaire Vadim Ermolaev,58,his mistress,Anna Nasobina,46,and their young son on Monday night.

The woman,who has not yet been named publicly,was filmed outside the ‘Sun’s Palace’ – a lavish apartment block owned by Mr Ermolaev.

It was in the foyer,just before 9pm,that a dumped rucksack exploded after the woman triggered it using a mobile phone.

Ms Nasobina had her legs amputated following the blast,while both she and Mr Ermolaev suffered severe shrapnel wounds and burns.
