MADRID (AP) โ Police clashed for a second night Tuesday with protesters who oppose negotiations between Spain's acting government and Catalan separatist parties over a possible amnesty for thousands involved in Cataloniaโs independence movement.
Several protestors in Madrid waved Spanish flags and shouted insults against the acting prime minister, Pedro Sรกnchez, and some of them self-identified as โnazisโ in chants. The protesters pushed against barriers set by police in riot gear, who responded with rubber bullets and by hitting the protestors with batons.
The government said that Tuesday's gathering at the gates of the national headquarters in Madrid of the ruling Socialist Party was attended by around 7,000, roughly double the number of protestors that took part the day before. There were other similar protests in other Spanish cities.

Three people were arrested Monday, the central authorities' representative in the Spanish capital said, including two men for violent behavior against police and one woman for disobedience.
A spokeswoman of the far-right Vox party, which holds the third-most seats in the national Parliament, said Tuesday that the party did not back the violence seen at the gatherings, but that it supported the anti-government protest. Vox's leader, Santiago Abascal, attended Monday's event in Madrid.
Sรกnchez, the Socialists' leader, blasted the protests, saying they were being led by โreactionaries.โ
โ(I extend) all my warmth and support for the Socialist Party members who are suffering harassment by reactionaries at their local headquarters,โ Sรกnchez wrote on X, the social media platform formerly known as Twitter.

โTo attack the headquarters of Spainโs Socialist Party is to attack democracy.โ
Sรกnchez is negotiating with the Catalan separatist parties to receive their backing in his bid to form a new government and keep his center-left coalition in power following an inconclusive national election in July. But the two separatist parties have demanded a sweeping amnesty that would include their leaders who fled Spain following their failed 2017 secession attempt, in exchange for their votes in Parliament, among other concessions.
That has angered many in Spain, including leading opposition parties on the right who accuse Sรกnchez of bending to lawbreakers.
Spainโs conservative Popular Party, the main opposition party, has called for its own protest against the amnesty negotiations for Sunday, in public squares in each provincial capital.

โI am not going to allow that my country has to ask forgiveness to those who attacked its institutions,โ Popular Party leader Alberto Nรบรฑez Feijรณo said.
There had been other protests in recent weeks, but they had remained peaceful.
Sรกnchez has until Nov. 27 to form a new government or the Parliament will be automatically dissolved and new elections called for January.
Despite losing steam in recent years, Catalonia's separatist movement retains strong support in the wealthy northeast region including control of the regional government.
