Tokyo police stepped up patrols and imposed roadblocks in an effort to tighten security after a series of rocket attacks by radicals threatening to disrupt the May economic summit meeting of leading industrial nations. The Tokyo metropolitan police department said it is adding 6,000 officers to an already highly visible force of 10,000. Within the last week, small radical factions have claimed responsibility for rockets fired at the U.S. Embassy compound and the Imperial Palace in Tokyo and at police headquarters in Osaka. There were no injuries and little damage.
