1) Colonel Gaddafi claimed that the protests in Libya were caused by al-Qaeda, and that he was merely fighting terrorism, but many see this as a way for Gaddafi to gain international support for staying in power.
2) While al-Qaeda does have a presence in North Africa, there is no evidence they are directly involved in the Libyan protests, which seem primarily focused on ending corruption.
3) However, if the protests drag on and the rebels grow desperate, they may turn to al-Qaeda for aid, undermining future security in the region. International intervention aims to replace Gaddafi quickly before this can happen.
