(Adds casualties, details, army comment) GAZA, June 30 (Reuters) - Israel launched a second air strike in the Gaza Strip on Saturday, killing at least two Palestinians and wounding three, medics said, hours after killing three militant commanders in a separate attack. Medics in Gaza said a missile fired from an Israeli warplane struck a metal workshop at a refugee camp near Gaza City killing the owner and wounding four employees. An Israeli military spokesman confirmed there was a second aerial attack in Hamas-ruled Gaza, but gave no further details.
