Audio slideshow: Marching in anger
By Omar Chatriwala in Doha, Qatar
Thousands of people turned out on Qatar's streets on Friday to protest against the now more than two weeks of Israeli assault on the Gaza Strip.
The attacks have drawn an angry response from across the Arab world, while demonstrations against the war have been held from Sydney to Sao Paulo.
In Doha, about 15,000 people marched in a "day of anger" called by Islamic scholar Yusuf al-Qardawi.
