Egypt's President Abdel-Fattah el-Sissi has asked the public to be patient and grasp the extent of the challenges facing the country following a massive power outage.

In a nationally televised speech Saturday, el-Sissi said the power outage Thursday that halted the capital's subway, disrupted airport operations, took TV stations off the air and left cities without electricity for hours was in large part due to a debilitated infrastructure that needs billions of dollars and time to fix. He said he is already reaching out to investors to address the power crisis.

In his half-hour speech, el-Sissi said he understood the public's frustration but begged for patience. The failure of el-Sissi's predecessor to deal with the power shortage was one of the reasons fueling popular opposition against him.
