KABUL (Reuters) - A rocket hit the diplomatic district of the Afghan capital Kabul on Friday, close to most Western embassies, the Presidential Palace and the United Nations main office, a senior policeman said. Abdulghafar Sayedzada, head of Kabuls criminal investigation unit, confirmed the rocket hit the Wazir Akbar Khan area, also home to many well-off Afghans and foreign companies. One policeman was lightly wounded, a source from the city police command office told Reuters. There were no reports of other casualties. There was no immediate claim of responsibility for the attack.
