Asian markets mostly fell on Tuesday, with dealers spooked by an election in Italy that left no clear winner, leading to political uncertainty and fresh fears about eurozone stability.
The dollar and euro extended the losses suffered in US trade as investors absorbed the Italian results, while there was also concern about the lack of progress in Washington to avoid spending cuts due to take effect Friday.

Italy Tuesday looked headed for political deadlock as results from Sunday's election indicated there would be no clear winner, while the biggest gainer was a protest party run by a popular comedian.
The polls show that while the leftists won the lower house, the party run by former prime minister Silvio Berlusconi had more seats in the upper house.
Investors fear the outcome will lead to political stalemate in the country and a possible return to the dark days of the region's financial crisis if austerity measures introduced to cut Rome's huge debt pile are reversed.

The split vote in Italy wiped out the yen's Monday losses that were fuelled by reports Japan's government is likely to nominate a man to run the central bank who is in favour of more aggressive monetary easing.

Traders are also keeping an eye on US lawmakers to see if they can muster an agreement to avoid the imposition of $85 billion in budget cuts -- known as the sequester -- that will come in on Friday.
Analysts have warned that if less drastic cuts are not agreed, the still-fragile economy could slip back into recession.
