GAZA, Sept. 28 (Xinhua) -- Israeli troops stationed on the borderline between northern Gaza Strip and Israel on Friday opened fire and wounded two Palestinian civilians, medics said.

Ashraf al-Qedra, spokesman of the Hamas-run ministry of health, said that the two Palestinians are aged 22 and 19 years old, respectively, adding that they are brothers and were shot by Israeli soldiers' gunfire in northern Gaza Strip.

The Israeli army did not comment on the incident, where the two casualties were taken to a nearby hospital in northern Gaza Strip.

Israel has built up into the Gaza Strip a 300-meter security no- go zone area along the borderline between the Gaza Strip and Israel, where soldiers immediately open fire at anyone that approaches the area.

Israel has imposed a tight blockade on the Gaza Strip in June 2007 right after Islamic Hamas movement had violently seized control of the coastal enclave and kept its control on all the crossing points with the enclave.
