At least a dozen men ambushed Sri Lanka's cricket team with rifles, grenades and rocket launchers Tuesday, converging on the squad's convoy as it drove through a traffic circle near an eastern Pakistani stadium.

Seven players, an umpire and a coach were wounded, none with life-threatening injuries, but six policemen and a driver died.

The attackers struck as a convoy carrying the squad and match officials reached a traffic circle 300 yards from the main sports stadium in the eastern city of Lahore, triggering a 15-minute gunbattle with police guarding the vehicles.

The assault, just ahead of a match, was one of the worst terrorist attacks on a sports team since Palestinian militants killed 11 Israeli athletes at the 1972 Munich Olympics.

By attacking South Asia's most popular sport, the gunmen guaranteed themselves tremendous international attention while demonstrating Pakistan's struggle to provide its 170 million people with basic security as it battles a raging Islamist militancy.

Pakistani Prime Minister Yousuf Raza Gilani said the incident "has humiliated the country" and the head of the Interior Ministry, Rehman Malik, declared Pakistan was "in a state of war."

Malik told The Associated Press that authorities were investigating whether the attackers wanted to take hostages.

"We are looking at the possibility the gunmen wanted to hijack the bus and take it to a nearby building and create a drama," Malik said. "The way they came prepared and in large numbers indicates such a plan."

Tuesday's attackers melted away into the city, and none was killed or captured, city police chief Haji Habibur Rehman said. The attackers abandoned machine guns, rocket-propelled grenades and plastic explosives, Punjab police chief Khwaja Khalid Farooq said. They carried backpacks stuffed with dried fruit, mineral water and walkie-talkies — provisions also abandoned at or near the scene, officials said.

Authorities did not speculate on the identities of the attackers, but the chief suspects will be Islamist militants, some with links to Al Qaeda, who have staged high-profile attacks on civilian targets before.

The bus driver, Mohammad Khalil, accelerated as bullets ripped into the vehicle and explosions rocked the air, steering the team to the safety of the stadium. The players — some of them wounded — ducked down and shouted "Go! Go!" as he drove through the ambush.

Sri Lanka had agreed to this tour — allowing Pakistan to host its first test matches in 14 months — only after India and Australia backed out of scheduled trips over security concerns. The assault will end hopes of international cricket teams — or any sports teams — playing in the country for months, if not years.

Tuesday's attack came three months after the Mumbai terror strikes that killed 164 people. Those raids were allegedly carried out by Pakistan militants, and the assault in Lahore resembled them in many respects. Both were coordinated, used multiple gunmen, apparently in teams of two, who were armed with explosives and assault rifles and apparently had little fear of death or capture.

U.S. State Department spokesman Gordon Duguid told reporters in Washington that the United States "utterly" condemned "this vicious attack on innocent civilians but also on the positive relations that Pakistan and Sri Lanka are trying to enjoy."

Authorities will also consider possible links to Sri Lanka's Tamil Tiger separatist rebels who are being badly hit in a military offensive at home, though Sri Lankan military spokesman Brig. Udaya Nanayakkara said it was unlikely the group was involved.

Authorities canceled the test match against Pakistan's national team, and Sri Lankan President Mahinda Rajapaksa ordered his foreign minister to immediately travel to Pakistan to help assist in the team's evacuation.

A special flight is expected to bring the players home in the early hours of Wednesday, according to a Sri Lankan Foreign Ministry official.

TV footage of the attack showed at least two pairs of gunmen with backpacks firing from a stretch of grass and taking cover behind a small monument before moving on. It was taken from the offices of a Pakistani news channel overlooking the site of the ambush.

"These people were highly trained and highly armed. The way they were holding their guns, the way they were taking aim and shooting at the police, it shows they were not ordinary people," said Salman Taseer, the governor of Punjab province. "This is the same style as the terrorists who attacked Mumbai."

An Associated Press reporter saw police handling what looked like two suicide jackets.

"It is a terrible incident, and I am lost for words," said Steve Davis, an Australian who was to have umpired the match.

Lahore police chief Rehman said "between 12 and 14 men" took part in the assault and they resembled Pashtuns, the ethnic group that hails from close to the Afghan border, the stronghold of Al Qaeda and the Taliban. He said officers were hunting them down.

Two Sri Lankan players — Thilan Samaraweera and Tharanga Paranavitana — were being treated for bullet wounds in a hospital but were stable, said Chamara Ranavira, a spokesman for the Sri Lankan High Commission.

Umpire Ahsan Raza was hit in his abdomen, medical Superintendent of the Services Hospital, Mohammad Javed, said.

Team captain Mahela Jayawardene and four other players had minor injuries, the Sri Lankan Cricket Board said. Ranavira said British assistant coach Paul Farbrace also sustained minor injuries.

Haider Ashraf, another police officer, said six policemen and a driver of a Pakistan Cricket Board vehicle were killed.

Sri Lankan Foreign Secretary Palitha Kohona said little could be done to stop such an attack, saying "there is never enough security to counter a well organized and determined terrorist group."

The Dubai-based International Cricket Council condemned the attack. But ICC President David Morgan told the British Broadcasting Corp. that the organization had no role in deciding on whether Pakistan was safe enough for a tour since Sri Lanka and Pakistan agreed to the match.

One militant group likely to fall under particular suspicion is Lashkar-e-Taiba, the network blamed for the Mumbai terror attacks in November, in which 10 gunmen staged a three-day siege targeting luxury hotels, a Jewish center and other sites.

In the past, India and Pakistan have blamed each other for attacks on their territories. Any allegations like that will trigger fresh tensions between the countries, which are already dangerously high.
