Amnesty International has urged Iran to allow international observers to monitor trials of more than 100 people accused of involvement in protests following June's presidential election. "The trial now going on in Tehran appears to be nothing but a "show trial' through which the supreme leader and those around him seek to de-legitimize recent mass and largely peaceful protests and convince a very skeptical world that Mahmoud Ahmadinejad was re-elected fairly for a second term as president," said Amnesty Secretary General Irene Khan.
