May 17 (Reuters) - The Pentagon on Monday identified six former Guantanamo detainees who it said were released from the U.S. military prison in Cuba only to rejoin the fight against American and coalition forces in Afghanistan.

Following are names and descriptions of the six, whom the Pentagon said were among 30 released prisoners who have resurfaced as fighters.

* Mohamed Yusif Yaqub, also known as Mullah Shazada -- Released May 8, 2003, he assumed control of Taliban operations in Southern Afghanistan and died fighting U.S. forces on May 7, 2004;

* Abdullah Mahsud -- Released in March 2004, he became a militant leader within the Mahsud tribe in southern Waziristan and directed the October 2004 kidnapping of two Chinese engineers in Pakistan. Pakistani forces killed five of the kidnappers during a rescue. Mahsud was not among the dead;

* Maulavi Abdul Ghaffar -- Captured in early 2002, he was held at Guantanamo for eight months and later was reported to have become the Taliban's regional commander in Uruzgan and Helmand provinces where he carried out attacks on U.S. and Afghan forces. He was killed in a raid by Afghan security forces on Sept. 25, 2004;

* Mohammed Ismail -- Released from Guantanamo in early 2004, he was recaptured four months later in May while participating in an attack on U.S. forces near Kandahar. When captured, Ismail carried a letter confirming his status as a Taliban member in good standing;

* Abdul Rahman Noor -- Released in July 2003, he has since participated in fighting against U.S. forces near Kandahar. After his release, he was identified as the man described in an Oct. 7, 2001, interview with Al Jazeera television as the "deputy defense minister of the Taliban."

* Mohammed Nayim Farouq -- Released from U.S. custody in July 2003, he quickly renewed his association with Taliban and al Qaeda members and has since become "reinvolved in anti-coalition militant activity."
