Description:

def put_targets(Rule, Targets,
             region=None, key=None, keyid=None, profile=None):
    '''
    Add the given targets to the given rule

    Returns a dictionary describing any failures.

    CLI Example:

    .. code-block:: bash

        salt myminion boto_cloudwatch_event.put_targets myrule [{'Id': 'target1', 'Arn': 'arn:***'}]

    '''
    try:

            Targets = salt.utils.json.loads(Targets)
        failures = conn.put_targets(Rule=Rule, Targets=Targets)
        if failures and failures.get('FailedEntryCount', 0) > 0:
            return {'failures': failures.get('FailedEntries')}
