It's not Abu Hafs al-Masri is it by any chance? Cos he's dead too! (Died in a US air-strike during the Afgan invasion). There is a an Abu Hafs al-Masri brigade supposedly active in the insurgency, but they are just named after him.
The only other Egyptian called al-Masri that I can think of is Abu Hamza al-Masri, the london based cleric with the hook who is currently (I believe) doing time at Her Majesty's Pleasure for 'incitement to racial hatred' and 'incitement to murder'. (Personally I reckon he's an MI6 assest who's been shafted).
