Martin at nationalterroralert.com passes on new info about another arrest of a South African (or at least someone traveling with a South African passport) with suspected terrorist ties knocking at our Southern border:

A South African citizen has been arrested in Mexico for alleged involvement in al-Qaeda-linked terrorist activities, South African media reported on Thursday, prompting further speculation about al-Qaeda presence in the country.

The man, so far unidentified, was carrying a South African passport and a mobile phone that had been used to make calls to South Africa when he was nabbed in Mexico near the US border on Tuesday, said local newspaper Thisday.

However, the South African government has yet confirmed if the man is genuine South African citizen or foreign national holding South African travel documentation.

Another newspaper, The Star, quoted a governmental official as saying that the 29-year-old with a Muslim name was arrested because the Mexican authorities believed his travel documents werenot in order.

If proved to be a South African, he would be the fourth South African citizen arrested overseas for alleged link with al-Qaeda in three weeks, said the newspaper.
