DUBAI (Reuters) - The death toll from a powerful explosion at Iran's biggest port of Bandar Abbas has risen to at least 25 dead, with more than 700 people injured, state media reported on Sunday, as firefighters worked to fully extinguish the fire.

President Vladimir Putin has ordered several planes to be sent to Iran to help deal with the aftermath of a blast at Iran's port of Bandar Abbas, Russia's emergency ministry said on Sunday.

Fires were still blazing on Sunday after a massive explosion tore through Iran's largest commercial port the day before, killing at least 28 people and leaving hundreds more injured, according
