 "Belgium police officers patrol the Grand Place in central Brussels, Belgium")
Metro lines and schools in Brussels have finally re-opened after the capital was shut down following fears of Paris-style attack.
According to Sky News, Police and security services will be deployed to guard the network as it is gradually opened to full capacity.
However, maximum security alert in Brussels will be extended until next Monday.
Prosecutors charged a fourth person with terrorist offences following the raids linked to the attacks.
Some 300 additional police officers and 200 soldiers will be deployed as the hunt continues for suspects involved in the Islamist militant attacks which killed 130 people.
