CAIRO, July 28 (Xinhua) -- The death toll of Sunday's clashes in some Egyptian governorates over ousted Islamist president Mohamed Morsi rose to three people, while about 50 others were injured, state-run news agency MENA reported.
In Port Said coastal governorate, northeast to Cairo, a 35-year- old man was burnt to death at a fragrance store and several others were injured when residents set fire to seven stores belonging to Muslim Brotherhood (MB) members, the main supporters of the deposed president.
The accident was an angry response after a teenager had been shot dead and 28 people were injured by Morsi's supporters, as the latter clashed with residents during a funeral procession of one of the victims of Saturday's clashes.
Morsi's Islamist supporters also opened fire at a church in Port Said and damaged some police vehicles and other cars of residents that carried posters of Defense Minister Abdel-Fattah al- Sisi.
Earlier on Sunday, also in port Said, 15 people were injured when a group of Morsi's supporters opened fire randomly at some opponents in the area around Al-Tawhid Mosque where they hold their pro-Morsi sit-in.
In Kafr al-Zayyat city in Gharbiya, to the north of Cairo, a 30- year-old MB member was killed by a penknife in the clashes that erupted at a graveyard when his group refused some local residents to attend a funeral procession of one of the victims of last night confrontations in Cairo.
The incidents followed similar bloody confrontations over the past two days that left at least 80 people killed and about 800 others injured, mostly in Cairo and Alexandria, according to official reports.
However, medical reports from the field hospital at Rabia al- Adawiya Square in Cairo, where Morsi's supporters staged a massive open-ended sit-in since June 28, said at least 200 pro-Morsi protesters were killed and over 4,500 injured in Saturday's clashes with security forces.
The interior ministry and Morsi's Islamist supporters point fingers at each others over the responsibility for the bloodshed.
Also on Sunday, the armed forces arrested three masked men who were injured in gunfire exchange after they attacked a military checkpoint outside a national bank in Arish city in North Sinai governorate bordering Israel, MENA quoted a security official as saying.
The source added that a terrorist group also launched two rockets near North Sinai Security Department but the attack resulted in neither deaths nor property damage.
Terrorist groups rose in Sinai following the ouster of Hosni Mubarak in early 2011 due to deteriorating security conditions in post-uprising Egypt.
Since the ouster of Morsi by popular-backed military procedures earlier this month, Jihadist groups affiliated with the deposed president intensified armed attacks on security premises and checkpoints in the peninsula, killing dozens of security personnel and civilians and also a number of Jihadists.
On Saturday, the armed forces started a comprehensive military operation, dubbed "Desert Storm," to combat terrorism and violence in Sinai.
