In the past few days, Yasser Arafat has released from detention three Hamas terrorists who were involved in the June 1, 2001 attack at the Tel Aviv Dolphinarium, which claimed the lives of 21 Israelis, as well as additional attacks. The three - Kasem Nazal Suwei, Ibrahim Dahmas and A\'a Rahman Hamad, prominent Hamas killers from the Kalkilya area - had been detained by PA police on various dates in the wake of Israeli and international pressure.



Kassem Suwei is the brother of Tzalah, the terrorist who perpetrated the July 1994 suicide bombing on a #5 bus in Tel Aviv which killed 21 people. Suwei was active in the gang that also included Said Hotri, the terrorist who perpetrated the Dolphinarium attack.



A\'a Rahman Hamad was involved in the suicide attack on the #5 bus and served six years in an Israeli prison for this. Immediately upon his release in October 2000, he became involved with the Hamas military command in the Kalkilya region.



Ibrahim Dahmas is also a member of Hamas\' violence unit. He was active in the gang that included Said Hotri (see above) and Fadi A\'amar, the terrorist who perpetrated the March 28, 2001 bombing at Neveh Yamin. Dahmas had also been planning to perpetrate a suicide attack himself.



During their detention, the PA police refrained from questioning the three and sufficed with holding them under lax supervision in comfortable quarters. Hamas exerted considerable pressure on the PA to release them. Last week, \"the door again revolved,\" and they were set free.
