In an attempt to gain entry into Macedonia, hundreds of migrants have rushed at Macedonian border to enter the country from Greece.

Latest reports claim that some families have managed to get through but many more people are being held back.

On Thursday, Macedonia declared a state of emergency to cope with migrants - many from the Middle East - who are trying to reach northern EU states.

The UN urged both Greece and Macedonia to tackle a "deteriorating situation".

Macedonian police earlier fired tear gas to disperse the migrants. Razor wire has been rolled across the frontier to prevent people from entering.

Some 44,000 people have reportedly travelled through the country in the past two months, meeting little border resistance.

Hundreds of migrants crushed their way towards the border's security forces on Friday afternoon.

The security forces beat back the migrants with truncheons and riot shields. A number of people fainted.

Medecins Sans Frontieres said it treated 10 people with wounds from stun grenades fired by Macedonian troops near the Greek border village of Edomeni.

The interior ministry on Friday said it would allow a "limited number of illegal migrants in vulnerable categories to enter Macedonia and they may be provided aid in accordance with the state's capacities". It gave no further details.
