SPARQL DELETE query Error: EOF while parsing

Question

I'm trying to delete some triples using this query:

deleteQuery = """DELETE { ?a ?b ?c } WHERE { mynamespace:List mynamespace:Item ?c. ?a ?b ?c }"""

My namespace is already defined, so that's not an issue. I'm not sure if I am using the correct syntax for the query though. When I issue the query I get this error:

400 EOF while parsing. Expected terminals: (prefix describe sum correlation select average modify insert median load ask construct clear count stats delete). Traceback (most recent call last): File "<stdin>", line 1, in <module> File "triple_store_methods_v2.py", line 40, in query myResults = myTupleQuery.evaluate() File "/usr/local/agraph-fse-3.3/python/franz/openrdf/query/query.py", line 358, in evaluate response = self.evaluate_generic_query() File "/usr/local/agraph-fse-3.3/python/franz/openrdf/query/query.py", line 239, in evaluate_generic_query checkVariables=self.checkVariables, accept=accept) File "/usr/local/agraph-fse-3.3/python/franz/miniclient/repository.py", line 80, in evalSparqlQuery accept=accept) File "/usr/local/agraph-fse-3.3/python/franz/miniclient/request.py", line 114, in jsonRequest else: raise RequestError(status, body) franz.miniclient.request.RequestError: Server returned 400: EOF while parsing. Expected terminals: (prefix describe sum correlation select average modify insert median load ask construct clear count stats delete).

I don't understand what I'm doing wrong. By the way, I am using AllegroGraph 3.3.

At a guess, I'd say that Allgegrograph (at least version 3.3) does not yet support SPARQL update.
