LONDON, Aug 23 (Reuters) - Iran reopened its embassy in London on Sunday, reciprocating hours after Britain restored diplomatic ties with Tehran, a Reuters witness said.

Iran's chargé d'affaires in London, Mohammad Hassan Habibollahzadeh, and Deputy Foreign Minister Mehdi Danesh Yazdi attended the ceremony at the Iranian diplomatic residence, a few doors away from the embassy in Kensington, West London.
