In one video, Abdul Ahmed Ali refers to Osama Bin Laden's warnings to the West.
Ali said: "Sheikh Osama warned you many times to leave our lands or you will be destroyed, and now the time has come for you to be destroyed.
"You have nothing but to expect that floods of martyr operations, volcanoes of anger and revenge and raping among your capital and yet taste that what you have made us taste for a long time and now you have bear the fruits that you have sown."
He condemned the British public for "showing more care and concern for animals than you do for the Muslim Ummah".
He added: "Stop meddling in our affairs and we will leave you alone, otherwise expect floods of martyr operations against you and we will take our revenge and anger, ripping amongst your people and scattering the people and your body parts and the people's body parts responsible for these wars and oppression decorating the streets."
The jury was also shown an extract featuring defendant Umar Islam wearing a traditional Islamic headscarf and sitting in front of a black flag covered with Arabic writing.
He dismissed the suggestion that any of the victims of bombings would be "innocent" because British citizens had paid taxes which funded the Army.
"Most of you are too busy watching Home and Away and EastEnders, complaining about the World Cup and drinking alcohol, too busy to care. I know because I come from that," he said in the video.
He added: "You call us terrorists but you can see we don't mind that if you call us terrorists 'cos we will keep on terrorising you until you learn your lesson.
"We love to die in the path of Allah."
In another extract he said: "This is revenge for the actions of the USA in Muslim lands and their accomplices, such as the British and the Jews.
"Now without doubt your dead are in hellfire, while the Muslims that die due to your acts will be in paradise.
"Martyrdom operations upon martyrdom operations will keep on raining on these kuffars (non-believers) until they release us and leave our lands."
Referring to wars in Iraq and Afghanistan, Islam said: "I say to you disbelievers that as you bomb, you will be bombed. As you kill, you will be killed.
"And if you want to kill our women and children then the same thing will happen to you. This is not a joke."
