A bomb on a train in Egypt killed four people including two policemen, officials said Thursday, while blasts in the Cairo metro and near a presidential palace wounded several others.

The makeshift bomb exploded in a carriage late on Wednesday as policemen inspected it after the train stopped at a station in the province of Menufiya north of the capital.

The train was not heading for Cairo.

The two policemen were killed on the spot while two passengers later succumbed to their wounds, a medical official said in an updated toll.

A bomb later went off in a Cairo metro station, wounding three people.

Another small blast in the capital struck outside the Al-Qubba palace, which is rarely used by President Abdel Fattah al-Sisi, lightly wounding a female passerby.
