A Yemeni man named by Saudi Arabia last month as one of its most wanted militant suspects has been in detention in Yemen under another name, the Saudi Interior Ministry said on Saturday. It said Zaid Hassan Humaid, one of 36 men whose names were published by Saudi Arabia in June, had been held in his native country for some time under the name Zaid Hassan Juaidi.The ministry also said Yemen had handed over 12 Saudi detainees. It gave no details of the men or why they had been arrested. Saudi Arabia has been battling suspected al Qaeda militants since May 2003, after they launched a wave of violence with triple suicide bombings at Western housing compounds in Riyadh. Last week Saudi security forces killed the man at the top of the list of 36 wanted suspects, Moroccan national Younis Mohammad Ibrahim al-Hayyari. One of the suspects flew back to Saudi Arabia from Lebanon and surrendered to authorities. Security sources say two or three men on the list have been killed in Iraq and another is in detention in northern Iraq.
