Despite the fact that Afghan President Hamid Karzai and U.S. Defense Secretary Robert Gates agreed it was not proved if Tehran was involved in war supplies to Afghanistan, Gates said Monday that Iranian weapons have begun flowing there.
Gates told a news conference at the presidential palace that he and Karzai had discussed the Iranian weapons issue.
"There have been indications over the past few months of weapons coming in from Iran," Gates said. "We do not have any information about whether the government of Iran is supporting this, is behind it, or whether it's smuggling, or exactly what's behind it."
The Iranian weapons are being supplied to the Taliban insurgents, he said, adding that some may also be headed to criminals involved in Afghanistan's drug trade. Gates did not specify what types of weapons were involved.
A NATO spokesman told reporters last week that a powerful type of roadside bomb like those used in Iraq, but never before seen here, was found recently in Kabul. The bomb, known as an EFP, or explosively formed projectile, was notable for its level of sophistication.
Asked separately whether he believed Tehran was behind the flow of weapons, Karzai suggested it was unlikely.
"There's no reason that any of our neighbors should support the Taliban," Karzai said. "We don't have any such evidence so far" regarding possible Iranian government involvement, he said, adding that relations between the two nations were improving.
"Iran and Afghanistan have never been as friendly as they are today," Karzai said.
Earlier in the day, during a stop at Camp Morehead, the head of the Afghan National Army said his country is pushing the United States to accelerate training and equipping his army so the Afghans can fight the Taliban on their own.
Gen. Bismullah Khan, the army chief of staff, told reporters traveling with Gates that the goal of attaining independence on the battlefield is essential.
"We don't have air support," he said through an interpreter, expressing frustration at the lack of an Afghan air force. "That is a very serious problem. We are looking forward to the day when we can fight the enemy independently."
He was asked how soon the army could reach that goal.
"We asked for it to be as soon as possible," he said. "I will ask the secretary of defense to expedite the process so we can do this. The only way to defeat the enemy is to become independent."
He mentioned that the United States has committed, with the help of allies, to building an Afghan national army of 70,000 soldiers by the end of next year.
"But it's not going to be enough," he said. "We'll ask for more."
Gates, making his second visit to Afghanistan as defense secretary, came to this training camp some five miles southwest of Kabul to confer with U.S. and Afghan commanders training Afghan special forces.
Gates told reporters on Sunday that despite a rise in insurgent violence this spring, he remains convinced American and NATO forces are making steady progress against the Taliban.
For months, Gates has expressed concern about possible reversals in Afghanistan, which still lacks a self-sustaining military and suffers from the unmet expectations of building an effective central government.
On his first trip, in January, he worried about Taliban incursions from havens inside neighboring Pakistan and said it appeared the Taliban were gearing up for a spring offensive.
Since then, levels of violence in Afghanistan have risen but the Taliban offensive has gained little of a foothold.
