Johannesburg - The United States of America have frozen the assets and imposed other sanctions on South African terror-accused twins, Brandon-Lee and Tony-Lee Thulsie, for plotting a series of attacks on behalf of the Islamic State terrorist group against Jewish targets and the US Embassy, according to reports on Tuesday.

“Among other consequences, all of Tony-Lee Thulsie and Brandon-Lee Thulsie’s property and interests in property subject to US jurisdiction are blocked, and US persons are generally prohibited from engaging in any transactions with them,” the release stated according to news agency Sputnik.
