Israeli Prime Minister Ariel Sharon (search) said Sunday he would keep hunting down Hamas militant leaders while pushing forward with his plan to evacuate all Gaza Strip and some West Bank settlements.

At the start of a weekly Cabinet meeting, Sharon thanked and praised the defense establishment for Saturday's "successful" operation, in which Hamas leader Abdel Aziz Rantisi (search) was killed.

Rantisi was killed in an airstrike less than a month after Hamas spiritual leader Sheik Ahmed Yassin (search) was killed in a similar attack.

"This policy of making an effort on the one hand to advance a political process and on the other hand to hit the terror organizations and their leaders will continue," Sharon said.
