A suicide blast at a restaurant wounded three people on Wednesday in the south-eastern Afghan town of Khost, a police official said.

The bomber died in the blast and the intended target might have been Afghan and foreign military officials who were meeting at a park about 300 metres away from the restaurant, the police official said.

Two women and a man were wounded by the blast in the restaurant, he told reporters.

He did not say who was behind the blast, but in the past, Taliban insurgents have carried out a series of suicide attacks and other raids in the town, which lies close to the border with Pakistan.
