Egypt's Transport Minister has admitted failings in the country's railways but defended years of investment in the network, after the latest in a series of deadly crashes. Appearing before parliament's transport committee on Tuesday in a session that ran for about six hours, Lt Gen Kamel El Wazir said he was mourning the seven people killed in Sunday's collision at El Ayyat and that passenger safety was his responsibility. The Health Ministry said 125 people were injured in the crash.
