Seven Christian Workers Beheaded - VOM Sources
The bodies of seven Christian workers were recovered in Parang town where they were kidnapped by Abu Sayyaf Muslim extremists. VOM sources report that the Christian workers' bodies were found in the jungles of Jolo by soldiers, days after they were seized while heading to a government road project. Pray for comfort for these families and ask God to use the testimony of the slain believers to bring non-believers into the knowledge of Him. 2 Corinthians 1:3-7

So, I'm wondering. At what point does adding the word "extremists" after "Muslim" start to become redundant?
