ISTANBUL, Turkey (Reuters) - Three tremors ranging up to 5.0 on the Richter scale shook
 the Turkish-Iraqi border region on Saturday, Turkey's main observatory said.

 ``These are not of the scale that would cause any damage,'' a spokesman for the Kandilli
 observatory in Istanbul told Reuters.

 The first tremor of magnitude 5.0 struck at 10:18 a.m. local time (3:18 a.m. EST). It was
 followed by a 4.0 tremor at 11:29 (4:29 a.m. EST) and another of 3.8 at 11:35 (4:35 a.m.
 EST).

 Two devastating earthquakes hit Turkey in August and November last year, killing at least
 18,500 people and wreaking widespread damage in the industrialized northwest.
