TEHRAN, Iran (AP) — A semi-official religious foundation in Iran has increased a reward it had offered for the killing of British author Salman Rushdie to $3.3 million from $2.8 million, a newspaper reported, days after protests coursed through the Muslim world over alleged insults to the Prophet Muhammad.

Hardline Jomhoori Eslami daily and other newspapers reported on Sunday that the move appeared to be linked to protests over an amateurish anti-Islam film, which crowds in some 20 countries said drove them to defend their faith — in some cases by attacking American embassies.
