DEMONSTRATORS in Melbourne yesterday joined worldwide protests against Israel's deadly attack on ships ferrying protesters and aid to the blockaded Gaza Strip. More than 1000 protesters brought traffic to a standstill in the city yesterday as they marched to Parliament Housechanting ''Free, free Palestine'' and ''Shame, Israel, shame''. Across the Tasman, hundreds of anti-Israel protesters hurled old shoes at the US consulate in Auckland on Saturday in an ''expression of outrage and anger'' over clashes between Israeli armed forces and Gaza-bound aid workers. The demonstration called for sanctions against the Israeli government. Protests also took place in Wellington, Christchurch and Dunedin. Tens of thousands of protesters poured into the streets of Alexandria, Egypt, calling for an end to Israel's three-year blockade of the Gaza Strip. About 20,000 protesters also vented their anger at Israel over its attack on the Gaza flotilla.
