An Afghan soldier attacked foreign troops at a military base in the north of the country on Saturday, officials said.

An unspecified number of US soldiers were injured in the attack that took place at a base in the Dehdadi district of Balkh province, located some 540 km to the northwest of Kabul, a Defence ministry spokesman told Efe news.

"A soldier opened fire on foreign troops inside Camp Shaheen. We only have reports of injured foreign troops," said Muhammad Radmanish, the ministry's spokesman.

A spokesman for the US military command, based in Kabul, dismissed reports that American soldiers had been killed.
