History repeats itself: Israel attacks UN observers in Lebanon
Nothing to do with Algeria, but, if you were surprised by Israel's recent attack on UN observers in Lebanon, it has its precedents:
The UN quickly discovered [in 1980] that the Israelis were physically present at Haddad's artillery positions during bombardments, presumably to help the militiamen with their coordinates. Cynicism replaced pride. 'I got a call from an Israeli officer over the radio,' a Dutch officer in Haris told me. 'He wanted to warn me that the Christians were likely to fire in our direction. He wanted me to know that it wouldn't be Israel's fault, because they were trying to warn us. The Israeli came on the radio, made his excuses and shouted: "The Christians are going to fire in about six seconds - five - four - three - two - one." And a couple of seconds later, shells started landing behind the United Nations lines. How was he so accurate? He wanted me to know he was next to the artillery battery. He was doing the shooting.' (Robert Fisk, Pity the Nation: Lebanon at War, Oxford University Press 1990, p. 151).
Oh, and obviously more recently the Qana Massacre.
