For the second time in four days, a bomb exploded Thursday at a store operated by a native of Jordan. There were no injuries and damage was minimal.

"It could be because of politics," said Jordanian native Maymooh Alami, who operates the West End Food Market. "I am very concerned. Some people hate you for your personality. Some people maybe want to put you out of business."The store is in a building owned by another native of Jordan, Tom Nassar. Federal officials investigated Monday's and Thursday's bombings, but FBI agent Paul Mallett attributed the blasts to random violence and not to the U.S. invasion of Iraq.
