A Palestinian student from Birzeit University pushes a burning tire with his foot during clashes with Israeli soldiers for the second consecutive day as they protest against the ongoing Israeli offensive on the Gaza Strip in the West Bank town of Betunia on November 18, 2012. Israel's Foreign Minister Avigdor Lieberman said that Israel would not negotiate a truce with Gaza Strip's Hamas rulers as long as rocket fire continues from the Palestinian enclave.
