An armoured bulldozer clears a path for Israeli troops during a military operation against Palestinian militants January 16, 2005 in Zeitoun near Gaza City in the Gaza Strip. Prime Minister Ariel Sharon said Sunday he was giving Israel's army free rein to battle militants in Gaza and accused the new Palestinian leadership he now shuns of doing nothing to stop attacks on Israelis.
