An earthquake with a magnitude of 5.6 on the Richter scale shook the southern Iranian island of Qeshm and caused damage to residential buildings in villages on Sunday, ISNA news agency reported. Several residential units in the villages Kavouhi and Zinabieh in the Dargehan area were damaged and two villagers slightly injured, the governor of Qeshm, Mehdi iran-Nejad, told ISNA. Relief aid and medical teams have already been dispatched to the quake site, the official said, according to DPA. The same island was hit by a 6.1 quake in September. That temblor killed at least six people, injured almost 50 and caused heavy damage to residential units in September.
