KABUL, Afghanistan — The U.S. military’s top general was meeting with senior officials in Afghanistan today to attempt to stop the recent wave of attacks by Afghan soldiers and police against international forces in the country.

Army Gen. Martin Dempsey, the chairman of the Joint Chiefs of Staff, landed at Bagram Air Field outside Kabul earlier in the day and was scheduled to meet with Gen. John Allen, the commander of NATO and U.S. forces in the country, and senior Afghan officials, said spokesman Jamie Graybeal.

“He’s certainly talking about a number of issues including progress with the (military) campaign and the like,” Graybeal said. “He’s also obviously talking about the insider attacks.”

In the latest such attack Sunday, two Afghan policemen turned their weapons on U.S. troops in Kandahar province, killing an American service member, officials said. That raised the death toll to 10 U.S. troops killed in such attacks in the space of just two weeks.

Sunday’s attack happened in Kandahar’s Spin Boldak district near the border with Pakistan. One of the attackers was killed when the troops returned fire and the other escaped, Graybeal said.

A U.S. Defense Department official confirmed that the dead service member was American.

The Taliban have been actively recruiting members of the Afghan security forces, saying in a statement last week that they considered these turncoat attacks a major part of their strategy against international forces.

Once an anomaly, these attacks have been climbing in recent months. There have been 30 such attacks so far this year, up from 11 in 2011.

On Saturday, Defense Secretary Leon Panetta called Afghan President Hamid Karzai to encourage him to work with U.S. commanders to ensure more rigorous vetting of Afghan recruits.

It was disclosed Friday that U.S. troops have been ordered to carry loaded weapons at all times in Afghanistan, even when they are on their bases. The order was a precaution against such insider attacks.

Meanwhile, in the eastern province of Paktia, three Afghans from a politically connected family were killed when their car struck a roadside bomb. Provincial police chief Zulmai Oryakhail said one of the dead had two brothers close to the government — one an adviser to President Hamid Karzai, and the other a former provincial governor and parliamentarian who is now a tribal leader.

The blast occurred outside of the provincial capital of Gardez, Oryakhail said.
