A report alleges that the number of pro-Iran militiamen have grown so large that they are the third largest military force in Iraq.
The statement said Russian army paratroop units were supporting the claimed advance by holding back Ukrainian forces on the flanks.
The new group, Battalion of Martyr Omar Abu Laila, is named after a terrorist who shot and stabbed a soldier and a civilian near Ariel, killing them.
The Ukrainian military said that as of April 2022, roughly 20,000 foreigners from 52 countries have applied to enlist – including some Israeli nationals.
