The Israelis disputed this claim, and the UN Peacekeeping force also dismissed the border crossing claim.[1] Lebanese sniper fire ensued. Both sides agree that the Lebanese issued a verbal warning prior to the shooting and the Israelis stood their ground and claimed they were on Israeli territory.[8] After an Israeli reserve lieutenant colonel was killed and a captain was shot and injured, the Israelis responded to the sniper fire from the Lebanese side of the border.[9] UN forces intervened to bring a halt to the armed conflict. Reporters Without Borders said the Israelis wanted to install a surveillance camera on the site of the tree.[4] This was the first armed incident since 2006 Lebanon War and a violation of the UN Resolution 1701 to prevent further conflict.[10]
