ATHENS (Reuters/AFP) - A makeshift bomb exploded outside the residence of the head of the Pakistani community in central Athens early on Saturday causing damage but no injuries, police said. There was damage to the entrance of the apartment building and three cars but no injuries. There is no claim of responsibility, a police official said. It was the second incident in less than 24 hours as another makeshift bomb damaged the office of a far-right group in central Athens early on Friday without hurting anyone. Anonymous warnings made by telephone to a Greek television station and a newspaper 15 minutes before the explosion also enabled police to seal off the area. Media reports said the bomb targeted the home of the Chairman of the Greek-Pakistan friendship association. Later in day, a home-made bomb exploded outside a building housing immigration offices in Athens causing some damage but no one was hurt, police said. Police cordoned off the area after an anonymous caller warned a newspaper and a television network of the explosion which damaged a fence around the building in the Petrou Ralli district, a bus shelter and nearby shop windows. The device had been deposited in a bag near the shelter. The Pakistani community in Greece numbers several thousand members, most of whom live in the greater Athens area. Muslim migrants in Greece have faced increasing hostility from far-right militants in recent years, and the Pakistani community has frequently denounced attacks on its members by Greek youths. Saturdays first bombing occurred in the central Athens district of Agios Panteleimonas which has a strong immigrant presence and where protests both in favour and against foreigners have been held in recent months.
