The death toll rose Sunday in the Paris terror attacks with the deaths of three patients who had been critically injured, hospitals reported. The deaths brings the total to 132, with 349 injured, 96 critically.

The deaths came as French President Francois Hollande sought a three-month extension for the state of emergency imposed in the wake of Friday's attacks. Police also tweeted out a picture of a French national wanted in the attacks, identified as Abdeslam Salah.

A manhunt was underway for a suspected eighth attacker, following the discovery of an abandoned black Seat Leon in the Paris suburb of Montreuil, Seine-St. Denis. Police said they have identified three of the seven attackers who either blew themselves up or were shot and killed by police. The only name released so far was Ismael Omar Mostefai, 29, a French national.

U.S. President Barack Obama and Russian President Vladimir Putin met Sunday on the sidelines of the Group of 20 meeting in Turkey and agreed a concerted effort must be made to destroy the terror group. The meeting came as Turkish authorities thwarted a suicide bombing.

Investigators said the attackers communicated with the Islamic State group in Syria before the attack, the New York Times reported. They are believed to have used encrypted technology to avoid detection.

Seven people were in custody in France, and at least five others reportedly were arrested in Belgium. Two of the Paris attackers had lived in Belgium, the Belgium federal prosecutor said Sunday. Belgian Justice Minister Koen Geens acknowledged a car found abandoned near the Bataclan concert venue had been rented in Belgium.

Thousands of people around the world gathered to mourn Paris' dead, and memorials were set up in various places with flowers, candles and messages. A remembrance ceremony was scheduled for the Grande Synagogue de la Victoire in Paris, Jewish leaders said. A special mass was scheduled for Notre Dame Cathedral. Three official days of mourning began Sunday.
