Belgium under a Security lockdown over paris attacks.

Belgium's capital entered a security lockdown Saturday as the government warned of a threat of a repeat of Paris-style attacks, with subways in Brussels closed and heavily armed police and soldiers deployed. At least one suspect from the deadly Paris attacks is at large, and was last seen crossing into Belgium.

Prime Minister Charles Michel said the decision to raise the threat level was taken "based on quite precise information about the risk of an attack like the
one that happened in Paris ... where several individuals with arms and explosives launch actions, perhaps even in several places at the same time."

Authorities across Europe, the Mideast and in Washington are trying to determine how a network of primarily French and Belgian attackers with links to Islamic extremists in Syria plotted and carried out the deadliest violence in France in decades — and how many may still be on the run.


A new potential link emerged Saturday in Turkey, where authorities said they detained a 26-year-old Belgian suspected of connections to Islamic extremists — and possibly to the Paris attacks.

Belgium's national Crisis Center had raised its terrorism alert for the Brussels region to Level 4, which indicates a "serious and immediate threat." Belgium's special security Cabinet held an emergency meeting Saturday morning.

Brussels was home to the suspected organizer of the Nov. 13 Paris attacks, Abdelhamid Abaaoud, and Belgium has filed charges of "participation in terrorist attacks and participation in the activities of a terrorist organization" against three suspects relating to the Paris attacks.
