Insight - Foreign fighters seek Islamic state in post-Assad Syria

ALEPPO, Syria (Reuters) - Huddled around a fire in a bombed-out building in Aleppo, foreign jihadists say they are fighting for a radical Islamic state in Syria - whether local rebels trying to topple President Bashar al-Assad like it or not.

Among their fellow revolutionaries and civilians, these foreigners draw both respect for their iron discipline and fear that if Assad falls, they may turn on former allies to complete the struggle for an Islamic caliphate.
