In an abandoned kibbutz in Israel's evacuation zone near the Lebanese border, Lior Shelef has stayed behind to keep watch as a reservist in a protection force. The chicken coops had been damaged in a rocket attack and the frequent sound of explosions panics the animals. Over 2,000 rockets have been fired from Lebanon into northern Israel since the outbreak of the war in Gaza, when Lebanon's powerful Hezbollah group launched a campaign of attacks in support of Hamas Islamists.
