Cairo - Police in the Egyptian city of Alexandria fired tear gas at protesters on Friday, witnesses said, as nationwide rallies marked the second anniversary of the uprising that ousted Hosni Mubarak.

Clashes erupted in two neighbourhoods of Egypt's second city between police and protesters who burned tyres, sending plumes of dark smoke into the sky.

“The smoke is black, there is a lot of gas. There are people on the ground because they can't breathe,” one of the protesters, only identified as Rasha, told AFP. - Sapa-AFP
