+
+        Deletes a list of messages. This is similar to :func:`delete_message`
+        except it bulk deletes multiple messages.
+
+        The channel to check where the message is deleted from is handled via
+        the first element of the iterable's ``.channel.id`` attributes. If the
+        channel is not consistent throughout the entire sequence, then an
+        :exc:`HTTPException` will be raised.
+
+        Parameters
+        -----------
+        messages : iterable of :class:`Message`
+            An iterable of messages denoting which ones to bulk delete.
+
+        Raises
+        ------
+        ClientException
+            The number of messages to delete is less than 2 or more than 100.
+        Forbidden
+            You do not have proper permissions to delete the messages.
