Egypt: Both sides 'playing for time'

Talks between the Egyptian government and opposition groups on tackling the country's political crisis have failed to end protests in central Cairo.

Crowds of protesters, who have occupied the city's Tahrir Square for two weeks, say they will leave only when President Hosni Mubarak stands down.

The government offered a series of concessions at Sunday's talks, but the opposition said they were not enough.

The BBC's Jon Leyne in Cairo says that there is a sense negotiators on both sides are "playing for time".
