Insight - Saudi Arabia boosts Salafist rivals to al Qaeda in Syria

AMMAN (Reuters) - Alarmed by the rise of al Qaeda in Syria, Saudi Arabia is trying to strengthen rival Islamists with ties to Riyadh and this week helped engineer a consolidation of rebel groups around Damascus under a Saudi-backed leader.

That might bolster the opposition militarily as President Bashar al-Assad's forces have been pushing back, but it also underlines al Qaeda's expansion in Syria - and the proliferation of splits among Assad's enemies, just as world powers are trying to corral them into talks with his government.
