get recent post problem

I am trying to make a recent post base on multiple categories but not all categories..

I have this code

<?php
                $args = array(
                    'numberposts' => '3',
                    'category' => '5');

                $recent_posts = wp_get_recent_posts( $args, OBJECT );
                foreach( $recent_posts as $recent ) : setup_postdata( $recent ); ?>
                    <div id="search-post">
                        <h1><a href="<?php echo get_permalink() ?>"><?php the_title(); ?></a></h1>
                        <p class="post-date">Posted on <span><?php the_time('F j, Y'); ?></span> at <span><?php the_time('g:i a'); ?></span></p>
                        <br />
                        <div class="search-content">
                            <?php the_excerpt();?>
                        </div>
                        <a class ="search-read" href="<?php echo get_permalink() ?>">Read</a>
                        <br />
                    </div>
                    <br /><br /><br />
                <?php endforeach; wp_reset_postdata();?>

problem is it results only the latest post regardless of categories and repeated it depending on numberposts.

what suppose to be the problem with my code?

I tried this
‘category’ => ‘5’ //no to avail
‘category’ => ‘3, 5’ //no to avail
‘category’ => ‘local, international’ //no to avail
