Input: Consider Input: The heir to Saudi Arabiaâs throne has accused  Iran  of âdirect military aggressionâ which could be an âact of war â after Saudi air defense forces intercepted a ballistic missile on Saturday fired toward the capital  Riyadh  from across the border in Yemen.
Yemen has been embroiled in a civil war since 2015 between a Saudi-led military coalition in support of the Yemeni government  and Houthi rebels believed to be funded by  Iran .
âThe involvement of  Iran  in supplying missiles to the Houthis is a direct military aggression by the Iranian regime â the Saudi news agency SPA reported  Crown Prince Mohammed Bin Salman  as saying on Monday  âand may be considered an act of war against the Kingdom.â The language closely matched a statement earlier given by the Saudi-led coalition.
 Iran  immediately denied  it  was behind the missile launch.
The head of the Saudi military coalition said that experts in military technology had examined other missiles and âconfirmed the role of  Iran âs regime in manufacturing these missiles and smuggling them to the Houthi militias in Yemen for the purpose of attacking the Kingdom  its people  and vital interests.â
 The crown princeâs  reported remarks mark a new height in tensions between  Iran  and Saudi Arabia  the regionâs rival powers. The civil war in Yemen is widely seen to be a proxy war between the two countries  and has resulted in the deaths of over 10 000 civilians and triggered a humanitarian disaster including a cholera outbreak which has infected nearly a million people.

Input: Consider Input: But maybe â just maybe â this one game  this one Saturday afternoon at Madison Square Garden  is a hint that thereâs life yet in the old bear  in the St. Johnâs basketball team  which had no business sharing a court with the fourth-ranked Duke Blue Devils yet somehow walked off that court with an 81-77 victory.
âIâm happy for the guys â  St. Johnâs coach Chris Mullin  said. âThey needed it more than anything.â
It is what this program needed  too  as much as anything. As the losses mounted  the helplessness did too. Nobody expected  Mullin âs return to  his  Utopia Parkway kingdom to be a magic elixir  but nobody figured on 0-11 in the Big East in Year 3  either. It has been hard for  Mullin âs guys  yes  but it has been just as hard for the faithful to keep their faith.
âThe month of January was rough for us â forward Tariq Owens said. âBut  Coach  never stopped preaching to us and we never left the gym and finally it paid off.â
Itâs one game  yes. Two years ago   St. Johnâs  hammered a Syracuse team bound for the Final Four and  it  proved merely an outlier. Maybe this will be the same thing.
Or maybe it wonât be. If you care about St. Johnâs  and about college basketball in this city  it really is the only way to root.

Output: St. John
