Senior Judge Becomes Egypt's Acting President

Don't get comfortable

CAIRO — A senior jurist was sworn in as Egypt's acting head of state on Thursday as the military escalated what appeared to be a widespread roundup of the top Islamist aides to Mohamed Morsi, the country's first democratically elected president, who was ousted and placed under house arrest the day before.

In a ceremony broadcast live on state television, the chief justice of the Supreme Constitutional Court, Adli Mansour, took the oath as the country's temporary president, praising the protesters whose mass demonstrations spurred the Egyptian military to depose Mr. Morsi on Wednesday, suspend the Constitution and install an interim government. Mr. Mansour said the actions in Egypt had "corrected the path of its glorious revolution."
