Another night of violence in Turkey.
The sixth straight day of clashes between protesters and police.
Demonstrators are angry over what they say is Prime Minister Tayyip Erdogan's increasingly authoritarian rule.
Their latest demand -- that police chiefs be sacked for their violent crackdown on fellow demonstrators in preceding days.
The protests have drawn in a hodge-podge of groups - students, professionals - and now unions.
Earlier on Wednesday, over a dozen labor unions marched in the second day of a two-day warning strike.
Erdogan was in Tunis that day, on a North African trip that's been overshadowed by protests back home.
(SOUNDBITE) (Turkish) UNNAMED PROTESTER SAYING:
"People are finally awake. From now on they will never bow. You know, Prime Minister Tayyip Erdogan left the country. He is supposed to be back on Friday. We will see if he will come back."
The week of clashes has left two people killed and over 3,000 injured.
