SQL: Select all items and add info from left join where condition is met Background

I am creating a news site. Table NEWS has all news with unique ID news_uid. 

TABLE NEWS
--------------
news_uid | ...


If a user has read a certain news, that info gets stored in table NEWSREAD:

TABLE NEWSREAD
--------------
user_uid | news_uid | news_read
-------------------------------
A        | N1       | 1
A        | N2       | 1
B        | N3       | 1


So here user A has read News 1 and 2 and user B has read N3. 

Question

I am trying to create a SQL query that 


Selects all news from the news table
And tells me for a given user, which news have been read


Output:

news_uid | news read by user A
------------------------------
N1       | 1
N2       | 1
N3       | 0 (or NULL)


I have gotten so far, but this does not show N3 in the results. 

SELECT NEWS.news_uid, NEWSREAD.news_read FROM NEWS 
LEFT JOIN NEWSREAD ON NEWS.uid = NEWSREAD.news_uid 
WHERE NEWSREAD.user_uid = 'A' or NEWSREAD.user_uid IS NULL
SELECT NEWS.news_uid, NEWSREAD.news_read 
FROM NEWS 
LEFT JOIN NEWSREAD ON NEWS.uid = NEWSREAD.news_uid 
                  AND NEWSREAD.user_uid = 'A'
