Two South African brothers arrested on terrorism charges were plotting to blow up the US embassy in Pretoria and Jewish institutions, and planned to join the so-called I, police said Monday.

The 23-year-old twins, Brandon-Lee and Tony-Lee Thulsie, appeared briefly in a Johannesburg magistrate court after being arrested at the weekend.

"It is alleged that they wanted to bomb the US embassy and Jewish facilities in the country," Hangwani Mulaudzi, spokesman for South Africa's elite police, the Hawks, told AFP.
