DUZCE, Turkey (Reuters) - Dazed survivors and rescue workers searched in freezing temperatures on Saturday for signs of life in the rubble of Turkey's second devastating earthquake in less than three months.

Officials said at least 321 people died in the quake, which shook Turkey's northwestern province of Bolu on Friday evening. The jolt was felt in the capital Ankara and the commercial center of Istanbul. ``My Allah, the pain,'' said the Sabah daily of what it called Turkey's ``unending earthquake nightmare.''

 Aftershocks continued through Saturday morning as the army and the civil power, stung by accusations they had been slow to respond to August's quake, rushed to deploy rescue teams and heavy lifting equipment.

 Organizers said a summit of 54 leaders, including President Clinton, scheduled for Istanbul on November 18-19 would go ahead despite the disaster.

 Clinton was due in Ankara on Sunday. His wife Hillary and daughter Chelsea were expected in Turkey later on Saturday.

 More than 780 people were injured in the tremor, measuring 7.2 on the Richter scale, and hundreds were believed trapped in collapsed buildings. One entire lane of the main highway linking Ankara and Istanbul, at Bolu Mountain, collapsed into a ravine.
