Error while deleting triples from a graph in Blazegraph

Question

I am beginner in SPARQL and in my current task I have to delete some triples where the subject matches a specific string. I am running this delete query on a graph in Blazegraph.

This is my query:

prefix skos: <http://www.w3.org/2004/02/skos/core#>
prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#>

delete DATA {GRAPH <http://example.org/mapping>                      
{ ?s ?p ?o}
} 
WHERE { ?s ?p ?o .FILTER regex(str(?s), "omim") .}

However, I get this error after running the above query:

Was expecting one of:
    "base" ...
    "prefix" ...
    "select" ...
    "construct" ...
    "describe" ...
    "ask" ...

How should I modify the current query to delete the triples like this below:

s                                   p           o
<https://www.omim.org/entry/202110> rdfs:label  ADRENAL HYPERPLASIA, CONGENITAL, DUE TO 17-ALPHA-HYDROXYLASE DEFICIENCY
<https://www.omim.org/entry/202110> skos:exactMatch <https://identifiers.org/meddra:10000014>

Any help is highly appreciated.

DELETE DATA is for when you have specific triples you want to delete without any WHERE clause. You probably want DELETE { … } WHERE { … } instead.
