France's U.N. envoy warned late Tuesday that Iran faces the risk of a military strike if it pursues its nuclear drive because certain countries would not accept it having an atomic weapon.

In surprisingly frank comments at a New York panel discussion, Ambassador Gerard Araud followed up on President Nicolas Sarkozy's statement that there could be a "preventive strike" against the Islamic republic.

Iran's navy is going to deploy ships close to US territorial waters, its commander in chief was quoted as saying on Tuesday.

"As the global oppression (the U.S.) is present not far from our maritime border ... our navy is going to have a strong presence not far from U.S. territorial waters," the Irna news agency quoted Admiral Habibollah Sayyari as saying.

Four NATO peacekeepers and six Serb protesters were wounded Tuesday when violence erupted at a disputed crossing point between Serbia and Kosovo, officials said.

The violence came just hours before Belgrade was due to resume EU-mediated talks with Pristina aimed at calming tensions in majority-Serb northern Kosovo.

Sixteen wedding guests, including 11 children, were killed Tuesday when a bus hit a roadside bomb in western Afghanistan, underscoring the heavy toll paid by civilians in a decade of war.

A Turkish exploration ship is searching for gas and oil "close to" a Cypriot drilling zone off the divided Mediterranean island of Cyprus, a senior energy ministry official said Tuesday.

"Our ship is exploring gas close to the Greek Cypriot zone, and under the escort of Turkish naval vessels," the official told Agence France Presse, speaking on condition of anonymity.

At least seven people were killed as Typhoon Nesat smashed the Philippines on Tuesday, authorities said, with the capital Manila enduring waist-deep floods, blackouts and dramatic storm surges.

The Philippines is hit by about 20 major storms annually, many of them deadly, but the government said Nesat was one of the largest the country had faced this year, with its rain and wind path twice as big as average.

Three men suspected of plotting an attack on a Danish newspaper that printed controversial cartoons of the Prophet Mohammed in 2005 will go on trial in Norway next month, a state prosecutor said Tuesday.

More than 150 Spanish police raided a suspected al-Qaida financing ring Tuesday, arresting five Algerian men and seizing computer material, the government said.

Two metro trains collided in Shanghai on Tuesday, injuring more than 240 people, the system operator said, just months after a deadly high-speed rail crash that shocked China.

The firm blamed the accident on a signal failure -- the same cause as a July train crash that killed at least 40 people and shook public confidence in China's vast rail network.

A passenger was beaten to death by staff on a train in eastern China, state media reported, dealing a fresh blow to the rail industry's reputation following a fatal crash in July.

Three train staff seized the middle-aged man by the throat and savagely beat him after he intervened in an argument involving another passenger, Jiangxi Television, a local station, reported on Monday.
