A huge mob of football hooligans have been arrested in Paris for tearing through the streets after Morocco and France's World Cup victories on Saturday.
After France beat England 2-1 in Qatar, around 20,000 fans swarmed the Champs-Élysées in the French capital.
The mood started celebratory but soon turned violent when fans lobbing fireworks and projectiles at cops were met with tear gas and the officers' truncheons.
A large police response was deployed when thousands filled the avenue after Morocco beat Portugal earlier in the day, with fans chanting, beeping their horns and hoisting flags above them.
When France beat England, a larger swarm joined them and continued the celebrations.
Footage showed unruly fans clashing with riot police and smashing shop windows. Another clip appears to show rioters being beaten by cops after falling to the ground.
Images from the centre of the city showed riot cops holding up shields to protect themselves from incoming projectiles - which are said to have been large chunks of wood and rocks.
Flares and fireworks were also thrown, it has been reported.
A number of stores on the famed avenue were prepared for the night's celebrations, and had bordered up them up in anticipation.
French authorities said Friday they planned to deploy more than 1200 officers in the city to manage any unrest.
Ecstatic Moroccans poured into the streets of cities across the North African country and far beyond on Saturday, waving flags, honking horns and lighting flares to celebrate the national soccer team's historic victory over Portugal at the World Cup.
Morocco beat the Portuguese 1-0 in Qatar, knocking Cristiano Ronaldo out of the tournament and making the Atlas Lions the first African and first Arab team to reach the World Cup semifinals.
The capital, Rabat, was bursting with joy while Morocco fans also celebrated in the streets of Doha and in cities across Europe, where many Moroccans live. Other fans from the Middle East and Africa who have adopted the Atlas Lions as their team were also jubilant.
"We were so stressed as if we were on the pitch with the players, but now we want the trophy," said Mohamed Amine, celebrating in Rabat. "The players, this team lifted Morocco's reputation high among the nations of the world."
The victory has Morocco fans full of confidence for the days ahead. The team will face defending champion France in the semifinals on Wednesday.
"I am so happy that I don't even know if I can express myself, but if we are here now, I believe that we can make it to the final," Yasmine Benmehredj said during celebrations in the Moroccan capital. "I think we can win this World Cup."
In Qatar, hundreds of elated fans clad in green and red outside Al Thumama Stadium celebrated Morocco's win, chanting, ululating, banging on drums and waving the national flag. Some chanted: "Congratulations to us for this beginning! It will only go on and on!"
"This is unbelievable. It's the first time ever," said Saleh al-Rayes, a 27-year-old fan from Saudi Arabia in Doha.
As an Arab at the first World Cup held in the Middle East, al-Rayes said he feels a sense of inclusion and representation in the world of soccer, a spot that has been dominated by European and South American teams.
