CNN crew caught in police tear gas

Thousands of angry mourners gathered in a working-class Istanbul neighborhood today, for the funeral of a 15-year-old boy whose death Tuesday triggered the worst street violence Turkey has seen in months.

Berkin Elvan's death unleashed a wave of rage against the Turkish government.  His family has placed blame for the critical injury the boy suffered last June squarely on the government and police.

Last night saw serious unrest on the streets of Istanbul.  CNN Senior International Correspondent Ivan Watson and his cameraman were in the middle of it – caught between police and demonstrators, and struggling to report despite the debilitating effects of tear gas.

"This is an explosion of anger over the death of a fifteen year old boy," Ivan told Becky.  He had to briefly stop the segment in order to put on a gas mask, before resuming his reporting.

"We don't know where this is going to take Turkey right now," Ivan said.  "I, for instance, have never seen this major boulevard blockaded before by demonstrators who have set fire to roadblocks."

Ivan Watson will be reporting from Istanbul again tonight for the latest on the unrest.
