Suicide blast near US base in Kabul: officials

A suicide blast struck near a US military base in the Afghan capital on Friday, officials said.

"It was a suicide attack near Camp Phoenix," said Zemaray Bashari, spokesman for the Afghan interior ministry.

"We have no information on who it was targeted against and no information on casualties," he told AFP.

A spokesman for NATO, which together with the US military maintains more than 100,000 troops in Afghanistan, confirmed an explosion near the base.

"There was an explosion. We don't know what it was, but there was an explosion outside Camp Phoenix," said Sergeant First Class Kevin Bell.

Investigations had begun, he said.

Bashari said the area had been cordoned off by police.
