Ukrainian President Viktor Yanukovych to return to work

The political crisis has continued unabated in his absence, with thousands on the streets of the capital, Kiev.

Meanwhile, opposition leader Dmytro Bulatov has arrived in Lithuania for medical treatment.

Bulatov appeared on TV last week saying he had been abducted and tortured.

Yanukovych has not been seen in public since last Wednesday. His office says he had been suffering from a fever and breathing problems but that he was feeling well again and will go back to work.

Opposition leaders had previously expressed scepticism about his illness - on Sunday they again called on him to stand down while speaking to crowds of protesters in Kiev's Maidan square.

Thousands are currently in the square, which has become a focal point for the opposition.

Yanukovych has offered a number of concessions and his cabinet quit their jobs.

But the demonstrators, many of whom want to see closer ties with the EU rather than Russia, have not been placated.
