Israeli border police officers detain a Palestinian demonstrator during clashes after a protest against Israel's military operation in Gaza, outside Damascus Gate in Jerusalem's Old City. The latest upsurge in a long-running conflict was triggered on November 14 when Israel killed Hamas's military mastermind, Ahmed Al-Jaabari, in a precision air strike on his car. Israel then began shelling the enclave from land, air and sea. (Photo by Ammar Awad/Reuters)
