The state of emergency in France after the massacre in Paris may last for three months, French president Francois Hollande told a rare joint meeting of his nation's parliament Monday.

The parliament is set to receive a bill on Wednesday to prolong the state of emergency. It extends some police powers of search and arrest and limits public gatherings, among other changes.

Hollande also vowed to ramp up airstrikes against ISIS in cooperation with the U.S. and Russia, calling Syria "the biggest factory of terrorists the world has known." He said he had requested meetings with Presidents Barack Obama and Vladimir Putin to discuss pooling their efforts.

The French president said he wanted the talks "to unify our strength and achieve a result that has been too long in coming." Hollande called for "a union of all who can fight this terrorist army in a single coalition."

"[Syria is] the biggest factory of terrorists the world has known."

He did not specify whether he'd meet Obama and Putin together or separately.

Hollande also demanded more effective security for the European Union's external borders, so that the region would not have to return to national border controls.

The French president spoke to both the upper and lower houses of parliament at the Palace of Versailles. The meeting began with a moment of silence for the victims of the attack, and ended with lawmakers singing the French national anthem.
