Yemeni suicide bombers being trained in Somalia?

A couple of weeks ago, on March 15, four South Koreans were killed by a suicide bomber as the tourists were visiting the historic Yemeni town of Shibam, a UNESCO World Heritage site. Speaking to Reuters, an unnamed Yemeni security official claimed the bomber - Abdel Rahman Mehdi al-Aajbari - had been recently trained in Somalia to carry out the attack. The official said that Aajbari had left his home in western Yemen about two months ago.

Meanwhile, The Long War Journal's Jane Novak reports that al-Qaeda has claimed responsiblity for this suicide bombing. Her article, "Yemen's three terror fronts", also details a second, unsuccessful attack in the capital city of Sana'a, carried out three days after Aabjari's deadly bombing. In this incident, South Korean investigators and family of the deceased tourists were targeted as they drove in a convoy of cars by another suicide bomber. Novak writes that al-Qaeda's internet statement says these attacks are part of an effort to "expel the infidels from the Arabian Peninsula".
