SAINT-QUENTIN-FALLAVIER, France (AP) — The latest on the attack in southeastern France (all times local):
White House Press Secretary Josh Earnest says "the United States condemns in the strongest terms the terrorist attacks in France, Kuwait and Tunisia today."
Attacks Friday in those three countries as well as Somalia left over 80 people dead.
In a statement, Earnest said "our thoughts and prayers are with the victims of these heinous attacks, their loved ones, and the people of all three countries."
The spokesman added that "terrorism has no place in any society, and the United States will continue to work closely with our international partners to combat terrorist actors and counter violent extremism around the globe."
The U.S. Embassy in Paris is warning American citizens to be vigilant after a "terrorist attack" on a U.S.-owned gas factory in southeastern France.
The embassy released a statement Friday night urging Americans to report suspicious activities and stay away from any security incidents.
It also noted that French authorities have increased the terrorism alert level in recent months since attacks in January in Paris left 17 victims and three Islamic attackers dead, so there are more troops and police in the streets than in previous years.
French prosecutors say the suspect who they believe attacked a U.S. gas plant in France is a local truck driver who was known to workers at the Air Products plant.
Paris Prosecutor Francois Molins said Friday that the suspect, his wife, sister and another person who he would not describe further were in custody. He said the man found decapitated at the factory on Friday was the boss of the transportation company that the driver worked for in southeastern France.
Prosecutors' spokeswoman Agnes Thibault-Lecuivre told The Associated Press they haven't started asking questions about what might have motivated the attack and says it's too early to say whether there could be a connection to international terror groups.
French prosecutor says four people are in custody in an investigation into a beheading and an explosion at a gas factory in southeastern France and police are still searching buildings for evidence.
Paris Prosecutor Francois Molins said Friday the attacker was known to factory personnel because he came in regularly for deliveries. The attacker entered the factory grounds in a utility truck, then crashed the vehicle into a hangar at the site, prompting an explosion.
Molins says a knife and a decapitated body were found near the crashed truck and the body's head was found hanging on a gate. The head was surrounded by two flags carrying Islamic declarations.
Molins said the attacker, his wife, sister and another suspect are in custody. He said investigators are trying to determine whether there are accomplices.
The international police agency Interpol is offering its investigative help to Tunisia, France, Kuwait and Somalia after separate attacks that have killed more than 80 people.
Interpol said its Lyon, France, headquarters is in close contact with authorities in the four nations' capitals.
Interpol Secretary-General Juergen Stock said the four attacks Friday "show the truly global dimension to current terrorist threats."
The United Nations, the United States and other countries around the world are condemning the attack on a U.S. gas factory in France as well as attacks in Tunisia and Kuwait.
The French attack Friday came on the same day as a gunman mowed down scores of tourists on a beach in Tunisia and a suicide bomber killed over two dozen worshippers at a Shiite mosque in Kuwait.
U.N. Secretary-General Ban Ki-moon said those "responsible for such appalling acts of violence must be swiftly brought to justice" and Interpol offered its help to all three nations.
In Washington, Pentagon spokesman Col. Steve Warren said it was too soon to tell whether the three attacks were the work of Islamic State extremists but added "we unequivocally condemn these terrorist attacks."
French President Francois Hollande says he is raising the security alert to the highest level for three days in the southeastern region where a suspect attacked an American gas factory.
Hollande spoke after a high-level security meeting Friday afternoon, hours after the attack on the factory left two people wounded. In addition, a local businessman was found decapitated at the factory site, along with banners carrying Arabic inscriptions.
French police say they have the main suspect in custody, along with the suspect's wife and others. Hollande says the key question is to determine whether there were any accomplices.
Three French officials say the decapitated victim found in an attack on an American gas factory in France was the suspect's employer.
The officials, who spoke on condition of anonymity because the investigation was ongoing, said the victim was believed to have died before the suspect got a car through the factory's gates and rammed into gas canisters Friday morning. That triggered an explosion that officials say injured two people.
A French police official says the man in custody, Yassine Salhi, is a resident in his 30s of the Lyon suburb of Saint-Priest. Police have not named his employer but say he is the head of a local transportation company.
A French police intelligence official tells The Associated Press that the man detained in connection with an attack on an American gas factory in France has been identified.
He says the man in custody, Yassine Salhi, is a resident in his 30s of the Lyon suburb of Saint-Priest.
Security officials picked up two people from Salhi's apartment Friday afternoon. Another security official, who spoke on condition of anonymity because she was not authorized to speak with the media, said one of them was Salhi's wife.

Live television from France has shown two people — a woman and another person whose head was covered — being led away by French security forces from the detained suspect's apartment building in Saint Priest, a suburb of Lyon.
France's top security official says the suspect himself was detained earlier Friday after he rammed a car into gas canisters at an American gas factory in southeastern France, touching off an explosion that injured two people.
A security official says the suspect's wife was among those taken into custody Friday afternoon.
Another security official said the suspect apparently miscalculated about how explosive the chemicals he smashed into would be. French President Francois Hollande says a major explosion appeared to be the goal. Both spoke on condition of anonymity because they were not authorized to speak to the media.

A severed head was posted at the factory's entrance and Cazeneuve said authorities are still trying to identify the victim.
"People who could have participated in this abject crime are in custody after having been arrested," he told journalists.
The attack began when a car crashed the gate and plowed into gas canisters, touching off an explosion at the factory near Lyon on Friday morning.
Cazeneuve said the suspect was believed to be from the area and had been flagged in 2006 for ties to Islamic extremists, but surveillance was dropped in 2008.
