They include heptathlete Elizaveta Kamenets, European under-18 decathlon champion Alexander Komarov, long jumper Rail Kutuev and race walker Aleksey Shevchuk.

The clearance of Liliia Mendaeva, a national junior indoor 3,000 metres champion, only applies to the European Under-20 Championships.

The approval from the IAAF increases to 68 the number of Russian athletes given neutral status so far for the 2019 season.

A total of 15 applications have been rejected this year.

Some 42 athletes were in January given the green light to participate as neutrals in 2019, all of whom held the status in 2018.

Last month, Olympic long jump silver medallist Yelena Sokolova was among a further 21 Russians given permission to compete. 

The Russian Athletics Federation had previously revealed it had received applications from 133 athletes, with 98 of those having already been sent to the IAAF for consideration.

Those given neutral status were also invited to apply to compete at the 2019 IAAF World Cross Country Championships, scheduled to take place in Aarhus in Denmark on Saturday (March 30).

Athletes hoping to be given permission to compete at IAAF events must prove they are clean by showing evidence of their drug-testing history.

The IAAF's ban on Russia, first introduced in the wake of allegations of state-sponsored doping in November 2015, was extended for the 10th time earlier this month.

There remain two ongoing issues – agreed payment for costs incurred by the IAAF and the analysis of data now supplied by the Moscow Laboratory.
