This year’s Arbaeen congregation in the Iraqi holy city of Karbala hit a record high as millions streamed into the city after walking by foot from the holy city of Najaf, a shrine official tells Press TV website.

Millions of Muslims across the world observe Ashura, which commemorates the martyrdom anniversary of Imam Hussein (AS), the third Shia Imam.

Journalist and commentator Syed Zafar Mehdi says the Arba'een Walk is the largest and the greatest rally against all forms and manifestations of terrorism, fascism, imperialism, and despotism.

Iran's government spokesperson says more than three million Iranian pilgrims have so far flocked to neighboring Iraq to participate in the annual Arba’een commemorations, setting a new record.

The latest sandstorm in Iraq sends at least 4,000 people to hospital with breathing problems and leads to the closure of airports, schools and public offices.

It’s not merely a walk, it is a mark of protest against all forms and manifestations of terrorism, fascism, imperialism, despotism, and oppression perpetuated by state and non-state actors.
