Hong Kong protests: Clashes at Mong Kok site
Police and pro-democracy protesters have clashed in a battle for territory in the Hong Kong district of Mong Kok.
For the fourth night in a row, police charged after demonstrators breached their barriers, sparking scuffles that caused minor injuries on both sides.
The protesters are angry at China's rulers for limiting their choice of leader in the next election in 2017.
Leaders on both sides have called for calm, and confirmed that talks will take place on Tuesday.
Protesters, most of them students, accuse Hong Kong's current leader, CY Leung, of failing to stand up to the Chinese Communist Party.
Protests erupted last month and have been going on intermittently around government buildings and the business district, and in Mong Kok, a residential and shopping area in Kowloon.
On Friday morning, police had all but cleared the Mong Kok site and protesters' numbers had substantially dwindled elsewhere.
However, clashes resumed later that day as thousands of protesters launched a sustained effort to reoccupy a busy road junction in Mong Kok, and 26 people were arrested.
At about midnight on Saturday (16:00 GMT), police charged protesters, beating them with batons and deploying pepper spray.
A stand-off resumed shortly afterwards with neither side having gained any ground.
Carrie Lam, CY Leung's deputy, said Tuesday's talks would be focused on constitutional reform. Both sides will send five representatives to the negotiations, which will be broadcast live on television.
