A tense atmosphere lingered in Nanterre on Saturday following the funeral of a French teenager who was fatally shot by police in the Paris suburb earlier this week.

Arrests continued to mount with more than 1,300 people detained Friday overnight into Saturday and another 121 people arrested Saturday during the fifth night of nationwide protests in France after the 17-year-old’s death, according to the French Interior Ministry.

Family and friends gathered Saturday afternoon local time for the funeral service at a mosque in Nanterre. The funeral was solemn and quiet, according to CNN’s team on the ground, with people waiting in silence for his coffin to leave the mosque and be taken for burial. The teenager has been buried in the Mont Valérien cemetery in Nanterre, CNN’s team reported.

 
 

A heavy security presence was in place around the mosque.
