A bomb blast near the Egyptian supreme court in downtown Cairo on Monday killed one person, a police official said.

The explosion in the crowded district also wounded four people including a policeman, the official said.

It was not immediately clear whether a police checkpoint near the court and a metro station had been the target.

The attack came a day after two civilians died in a bombing outside a police station in southern Egypt.

Militants have regularly set off bombs in the capital, mostly targeting police, after the 2013 military overthrow of extremist president Mohamed Mursi unleashed a deadly crackdown on his supporters.

It was the second time a bomb went off near the supreme court, after an explosion wounded 12 people last October.
