Revelers around the world welcomed 2007 with fireworks and parties Monday.
Celebrations in Romania and Bulgaria took on a special tone with the entry of those countries in the European Union, but the holiday was overshadowed by bombings that led to the cancellation of events in Thailand.
Six bombs were set off in Bangkok, the capital, injuring at least 25 people.
Celebrations were called off after the bombing in the early evening at several busy locations. Officials feared people gathered to celebrate the could be targets of further bombs.
Initial suspicion was cast on southern Muslim militants, who have been waging an increasingly bloody separatist struggle in Thailand's three southernmost provinces over the past three years, or groups opposed to the current military-installed government.

In the German capital Berlin, gale force winds kept the city's emergency services busy on Sunday, but officials said the capital's spectacular New Year's Eve party would go ahead as planned.
More than one million people were expected to throng the main boulevard heading from the landmark Brandenburg Gate for a night of partying and a spectacular midnight fireworks display.
Top DJs and groups such as the Scissor Sisters and Sugababes were to entertain the New Year revellers on three stages and disco tents erected along the 2-kilometre route.
Opening acts were Bulgarian rock band Roberta and Romanian group Sistem - invited to mark the two countries' accession to the European Union on New Year's Day.

Just before midnight actor Jan Malmsjo recited Alfred Lord Tennyson's poem Ring Out Wild Bells, in a tradition introduced at Skansen in 1895.
Queen Margrethe of Denmark and King Harald of Norway held televised addresses earlier on New Year's Eve.
The queen touched indirectly on the crisis triggered by a Danish newspaper's controversial publication of caricatures of the Prophet Mohammed that sparked protests in several Muslim countries in 2006. She called for tolerance and mutual understanding.
'We know better what we stand for, what we can and cannot compromise on,' the queen said, adding that immigrants 'should not be expected to jettison all their experiences.'

Among the first to usher in 2007, Sydney provided a huge fireworks display for its New Years celebration.
As many as 1 million Sydneysiders braved wind to welcome 2007, but predicted rain stayed away. And, as usual, the Harbour Bridge was the hub of the extravaganza.
The midnight (1100 GMT) fireworks show, billed as the biggest and best to date, lasted 13 minutes and featured pyrotechnics displays off CBD buildings, the bridge and harbourside locations.
The 4-million-Australia-dollar (3.2-million-US-dollar) festivities were dubbed 'a Diamond Night in the Emerald City.'
In her New Year's Eve message, Sydney Lord Mayor Clover Moore said the city could make a shared commitment to strengthening the community and extending goodwill and optimism into 2007.
'Today we are truly part of the one global village and I hope we can also remember those who do not share our great good fortune in living in this peaceful, lucky country,' Ms Moore said.
In New Zealand, where it is mid-summer, unseasonably cold and wet weather put a dampener on celebrations in many parts of the country.

Rain also took the shine off festivities in key tourist centres including Taupo, Gisborne and Whangamata on the Coromandel Peninsula where thousands of summer vacationers gathered for the annual summer holidays.
