Analysis: the terrorist leader had been ill and key tasks are likely to have been handled by others for several years
Ayman al-Zawahiri was a low-key but effective leader of al-Qaida whose death will cause the terrorist organisation some short-term turbulence but is unlikely to cause any major long-term problems.
A decade ago, killing Zawahiri would have made a major difference. Now, though the nature of his death demonstrates the US’s continuing ability to strike individual enemies even in hostile environments and raises questions about the Taliban’s relationship with extremist groups, it is unlikely to weaken al-Qaida significantly.
