US admits mistakes over killings of Pakistan troops

The US military has admitted it bears significant responsibility for last month's air strike on the Afghan border that killed 24 Pakistani soldiers.

A statement said US and Afghan troops acted in self defence, but conceded there had been a lack of proper co-ordination with Pakistani forces.

A Pentagon spokesman later expressed "deep regret" over the incident.

In retaliation for the killings, Pakistan has closed its border with Afghanistan, cutting Nato supply lines.
