Delete statements running with EXECUTE IMMEDIATE command giving ORA-00933: SQL command not properly

I am executing a pl/sql block where i am fetching delete statements from a cursor and then running them
using EXECUTE IMMEDIATE command. The problem is that it gives error after executing some statements.
First six statements are executed fine and then gave 'ORA-00933: SQL command not properly ended' while
executing seventh statement.

--Below is how the code looks like:-
----------------------------------------
DECLARE
   TYPE r_cursor IS REF CURSOR;
   c_delete_cur           r_cursor;
   v_sql_stmt             CLOB;
   v_delete_stmt          CLOB;
BEGIN
   v_sql_stmt :=
      ncr_xx_pkg.getdeletescript ('NCR_MFS_SFW_TASKS_D',
                                  'NCR_MFS_SFW_TASKS_E'
