If a location is a legitimate military objective, it does not cease to be one because civilians are in the vicinity. As Article 28 of the 4th Geneva Convention provides:
The presence of a protected person may not be used to render certain points or areas immune from military operations.
Clearly, the deliberate placing of military targets in the heart of civilian areas is a serious violation of humanitarian law, and those who chose to locate such targets in these areas must bear responsibility for the injury to civilians which this decision engenders. As international law expert Yoram Dinstein notes:
Should civilian casualties ensue from an attempt to shield combatants or a military objective, the ultimate responsibility lies with the belligerent placing innocent civilians at risk.
In light of that, examine this visual proof of rocket firing by Hezbollah from within Qana and the use of human shields throughout Lebanon by firing and hiding amongst the civilian population:
Israeli PM Ehud Olmert made the following statement on Qana today: "I express my deep regret, shared by the entire State of Israel and the IDF, for the death of civilians in the village of Qana. Qana was used for launching rockets at Kiryat Shmona and Afula. All residents were warned to leave. There are hiding places for rockets inside the village, and the village itself constitutes a shelter for rocket launchers. We have no policy of killing innocent civilians. For 18 days thousands of missiles have been fired, aimed at murdering innocent civilians in the north."
Israeli FM Tzipi Livni made this statement today on Qana: "Israel expresses its deep regret at the loss of innocent life in the campaign against Hezbollah. Israel will undertake a thorough and comprehensive examination of the circumstances of today's events in Qana. During recent weeks Israel has been engaged in defending its citizens from constant attacks by Hezbollah on the towns and cities of northern Israel. Throughout these operations, the Israel Defense Forces has made strenuous efforts to avoid harming Lebanese civilians, which would be antithetical to the values of Israeli society. To our sorrow, Hizbullah repeatedly uses the Lebanese civilian population as human shields for its terrorist attacks. It is important that today's tragedy not divert the international community from the correct direction of finding a solution to the crisis by means of the complete implementation of United Nations Security Council Resolution 1559. Israel will not agree to return to a situation in which Hezbollah holds the stability of the region hostage."
