“Egyptian prosecutors escalated what appeared to be a widespread roundup of top Muslim Brotherhood members on Thursday, acting hours after the military deposed Mohamed Morsi, the Islamist who became the country’s first democratically elected president just a year ago,” the New York Times reports.

“The roundup, which placed some Brotherhood members in the same prison holding Hosni Mubarak, the autocratic leader toppled in the 2011 revolution, came as a senior jurist was sworn in as the acting head of state.”

The Washington Post notes that just last night President Obama had warned Egypt’s powerful military “to avoid any arbitrary arrests of President Morsi and his supporters.”

The Week: The dangerous precedent of Morsi’s ouster.

Egypt’s military deposed Mohamed Morsi, “the nation’s first freely elected president, suspending the constitution, installing an interim government and insisting it was responding to the millions of Egyptians who had opposed Mr. Morsi’s Islamist agenda and his allies in the Muslim Brotherhood,” the New York Times reports.

“The military intervention marked a tumultuous new phase in the politics of the Arab world’s most populous country, which overthrew Mr. Morsi’s predecessor, Hosni Mubarak, in 2011.”
