Italian and chinese U.N peacekeeper soldiers use differential GPS device to locate a position in relation to the U.N-demarcated Blue Line border between Lebanon and Israel, after Lebanese army troops opened fire on an Israeli army bulldozer that had crossed the frontier near the border village of Maroun el-Rass village, south of Lebanon, Thursday Feb. 8, 2007. Prime Minister Fuad Saniora on Thursday denounced what he called Israel's violation of the Lebanese border, an act that provoked the first exchange of fire between the two countries' forces since just after last year's conflict between Hezbollah and Israel.
