Blasts hit Cairo on Arab Spring anniversary

Two explosions have hit Cairo, as an on-edge Egypt braces for mass demonstrations on the third anniversary of the Arab Spring uprising that toppled Hosni Mubarak.

The tensions come a day after four bombs killed six people and injured more than 80 in attacks targeting security forces in the capital.

Mubarak was forced to step down on February 11, 2011 after 18 days of demonstrations in which an estimated 850 people were killed.
