A haul of guns and ammunition has been found in Denmark after the arrest of four suspected Islamic State fighters.

Danish police believe the group detained near Copenhagen had been recruited by the militant group in Syria to carry out attacks.

The cache of weapons were recovered in a connected search.

The police said in a statement: "The arrests took place as part of efforts to combat people enlisting in terrorist groups in the war-torn areas in Syria and northern Iraq".

All four are due to appear at a hearing before a judge on Friday.

The Danish intelligence service PET said last October that more than 125 people from the country are thought to have travelled to Syria and Iraq to join IS.

At least 27 of them are believed to have been killed there.

The security forces in Denmark have been on high alert since two people were killed in gun attacks on a free speech event and a synagogue in Copenhagen in February last year.

IS claimed responsibility for the suicide bomb attacks that killed 32 people in Brussels last month and the deadly rampage in Paris in November that left 130 dead.
