"We want an apology from France's government to the Muslim community. Otherwise we are asking our government and other Muslim countries to close French embassies."
Several hundred Afghans burnt the French flag as they chanted "Death to France" at a rally in the Afghan city of Jalalabad on Monday.
The protesters were demonstrating against the the French satirical magazine Charlie Hebdo's latest publication of a cartoon of the Prophet Muhammad, which devout Muslims deem an insult to Islam.
The protesters, mostly young Afghan men, also demanded the French Embassy in Kabul be shut down and that the French government apologise to Muslims.
It was the third straight day of protests across Afghanistan since the paper's first issue following the 7 January attack on its headquarters by Islamic extremists that killed 12 people.
