KHARTOUM, Sudan — Egypt’s first democratically elected president, Mohamed Morsi, was buried at dawn on Tuesday in a furtive and closely guarded ceremony attended by his wife and two sons.

Reporters were barred from the short ceremony and coverage of Mr. Morsi’s death was muted.

Only one major newspaper, Al Masry Al Youm, reported it on its front page, under a headline that failed to mention he was a former president. President Abdel Fattah el-Sisi has yet to make a public comment.

The stifled and uneasy reaction to the death of Mr. Morsi, the Muslim Brotherhood leader who collapsed and died in a Cairo courtroom on Monday, offered few indications about the legacy of a man who once represented the hopes for a democratic Egypt and has loomed in the background since his ouster by the military in 2013.

The Muslim Brotherhood, the Islamist group that swept Egypt’s first free elections and brought Mr. Morsi to power in 2012, has been driven deep underground by Egypt’s security forces. But the government’s response to his death was a telling indicator about the state of Egypt under the man who ousted him, Mr. el-Sisi, offering another dismal example of how the country has slid deeper into authoritarianism in recent years.
