Cairo Metro workers on the "Marg-Helwan" line stopped the metro after they went on strike to protest the resignation of Metro Company president Mohamed al-Sheemi. Metro drivers on the "Giza-Shubra" line reduced the trains' speed to 40 kpm (25 mph) from 80 kpm (50 mph), crowding metro platforms. Sheemi tendered his resignation to Minister of Transportation Ali Zain al-Abidin Heikal. Heikal accepted the resignation. Sheemi previously worked at the Ministry of Petroleum as vice president of "Sun Misr" before joining the Metro Company. He will return to his previous job.
