The publishers of an Egyptian political magazine said someone planted a bomb in their building near Cairo\'s Tahrir Square this weekend. aSecurity officers disarmed the remote-control device, which was found on a wall outside the office of Rosa El-Youssef, which Ahram Online said was a state-owned publication. A spokesman for the magazine said security in the area around Tahrir Square had been extremely tight ahead of planned political rallies marking the anniversary of the 1973 Arab-Israeli war. Security forces had been sweeping the area with bomb-detecting dogs and equipment. Ahram Online said Cairo and other Egyptian cities have been rocked by a series of bombings since the July ouster of President Mohamed Morsi.
