"The United States condemns in the strongest possible terms today's terrorist attack on the Dakaliya security directorate in Mansoura," State Department spokeswoman Jennifer Psaki said in a statement.

　　At least 14 people were killed and 130 others injured as a powerful explosion ripped through the police headquarters, local press reported.

　　Three bombs had been planted and two of them went off almost simultaneously. The third one in a car nearby was defused, a security official was quoted as saying. Egypt's Interim Prime Minister Hazem el-Beblawi condemned the attack as a "hideous" terrorist attack.

　　"The United States stands firmly with the Egyptian people as they work to put their country on the path towards democracy, stability and economic prosperity, in an atmosphere free from violence," Psaki said.
