CAIRO, Jul 17 (Aswat Masriya) - Six people were killed and three others were injured on Friday in clashes that broke out in the town of Talbiyah in Giza, a Health Ministry official said.

The ministry did not provide further details about the clashes.

Egypt observes the first day of Eid al-Fitr holiday today, which marks the end of the fasting month of Ramadan. Dozens of alleged Brotherhood supporters staged Eid marches to protest the death sentences served to their leaders.

Meanwhile, an Alexandria security official said that 20 "Brotherhood supporters" were arrested after security forces dispersed their rallies using teargas.

Egypt listed the Brotherhood as a terrorist organisation in December 2013. It insists it is behind the stringent wave of militancy which has targeted security personnel since the ouster of Islamist President Mohamed Mursi. The Brotherhood continuously denies the accusations.
