Bungoma Senator Moses Wetangula has become the first high ranking state official to mourn deposed former Egyptian President Mohamed Morsi.
In a tweet, the former Kenya's Foreign Affairs minister accused the current Cairo regime of instigating political charges against the 67-year-old who was first democratically elected president of Egypt.
"Mohamed Morsy, Egypt's only ever freely elected president but never let by the army to serve collapsed and died in a courtroom while facing spurious & politically instigated charges. He showed how one can rise from obscurity to high office. RIP MM," Wetangula tweeted.
According to State media, the former Muslim Brotherhood party leader died while attending a court session. He has been in jail since 2013.
"Morsi died today while attending a session in his trial on espionage charges. During the session, he was granted permission to address the judge," a presenter with Egypt's state TV was quoted by Al Jazeera.
It is reported that after the session was adjourned, the former president blacked out and then died.
The former president's son, Abdullah Mohamed Morsi, told Reuters news agency that the family did not know the location of his body. He added that the authorities had refused to allow Morsi to be buried at his family's cemetery.
Turkish President Recep Tayyip Erdogan was the first world leader to pay tribute to Morsi, calling him a "martyr."
"May Allah rest our brother Morsi, our martyr's soul in peace," said Erdogan, who had forged close ties with late former president.
Morsi took over in 2012 from longtime ruler Hosni Mubarak who was toppled during Arab Spring. He was overthrown a year later by the Egyptian Army.
