Protests have spread in central Athens, amid anger over austerity measures being debated by parliament.

Protesters threw stones and petrol bombs, and police fired tear gas. A number of people were injured and at least 10 buildings were set on fire.

MPs are discussing a bill to introduce the measures, which are being demanded in return for a 130bn-euro ($170bn; £110bn) bailout to avoid default.

PM Lucas Papademos warned that failure to pass it would be "disastrous".

The BBC's Mark Lowen in Athens says the violent protests, which have been common in recent months, are surprisingly large.

Several historic buildings, including cafes and cinemas, were in flames.

Syntagma Square - in the heart of Athens - is cloaked in a hail of tear gas, our correspondent adds.

Running battles with police are still continuing in parts of the capital.

Earlier, tens of thousands of people voiced their anger over the proposed bill outside the parliament building, in what was the second consecutive day of mass protests.

Some reports say as many as 80,000 people joined the demonstration in Athens, with another 20,000 protesting in Thessaloniki.

Analysts say the bill should still have enough support in parliament, with a vote expected within hours.

Lawmakers are also due to vote on a separate deal with private banks which could see 100bn euros of Greek debt written off.

If the measures are not approved, other eurozone nations and the International Monetary Fund (IMF) say Greece will get no money from them and will face bankruptcy in March.

Athens has to repay nearly 14.5bn euros in maturing debt on 20 March.

'Ground Zero' warning

The debate began in the early afternoon on Sunday, with the vote not expected until midnight (22:00 GMT).

Pasok, the largest party, and its coalition ally New Democracy - which have both backed the bill - account for more than 230 deputies out of a total of 300.

In a TV address on Saturday, Mr Papademos warned that Greece was "just a breath away from Ground Zero".

"The social cost of this programme is limited in comparison with the economic and social catastrophe that would follow if we didn't adopt it," he said.

Savings would be lost, the government would be unable to pay wages or salaries, and imports of fuel, medicine and machinery would be disrupted, he added.

The austerity measures include:

15,000 public-sector job cuts

liberalisation of labour laws

lowering the minimum wage by 20% from 751 euros a month to 600 euros

negotiating a debt write-off with banks.

They were presented to eurozone ministers in Brussels on Thursday evening.

The Greek cabinet has approved the measures but five government ministers resigned.

The eurozone bloc wants a further 325m euros in savings for this year and also insists that Greek leaders give "strong political assurances" on the implementation of the packages.

Greece cannot service its huge debt, and there are fears that a default could endanger Europe's financial stability and even lead to a break-up of the eurozone.

But many Greeks feel they are already squeezed almost to breaking point and cannot take any more cuts, our correspondent says.

Some are even saying Greece should leave the eurozone to be able to devalue its former currency, the drachma, and ease the debt stranglehold.

No-one care about Greece?

Greece is in the pooper so to say.

Leaving the eurozone would not be a bad idea. Out of all the places I have been, Greece is my favorite tourist destination. A cheap drachma would be really good for tourism.
Although I don't have any idea how their import/export situation is to predict the result of devaluing their currency.

It amazing that a country as insignificant as Greece can cause so much trouble.

they pay people by the month and not by the hour in greece?!

I can just talk about Germany, but here we have both systems. Wage by hour and wage by month, depends on where you work. 

I feel bad about those that gets their lives messed up thanks to the crisis but Greece screwed things up badly. They have to do something before it's too late (which it already might be).
I understand that people are angry at the government because, well, they are idiots and pretty much the whole world is angry at them. Rioting and destroying even more won't solve their problems though.

They should leave the Eurozone and go back to the Drachma...so I can go there for a cheap European holiday.

I agree that they are probably at their breaking point... Where else can they cut expenses? And jus for how long they think people are going to bear it? Probably leaving the Eurozone sounds like a good idea now, but dunno about their exports and the future outcomes if they were to do it...
