Greta Thunberg said last night that she was not aware that some of those involved in the 'freedom flotilla' voyage had previously shown support for Hamas and Hezbollah.

'I haven't heard about it or what this person has said,' the 22-year-old activist told Swedish media as she landed back in her home country.

When asked why she did not know about the views of people she was travelling with, she said: 'Because I haven't had a phone.'

She was then challenged by reporters who asked why she had not looked into the issue before she set off on the ship bound for Gaza.

'Should I ask exactly everyone what exactly they have said about everything?' she then asked curtly. 'It would take some time.'
