US President Donald Trump has condemned the attack on a synagogue in Pittsburgh - and called for the man responsible to face the death penalty.
At least 11 people have died after a man opened fire at a baby naming ceremony yesterday.
Four police officers who responded are also among the injured.
A suspect has been arrested and charged with 29 offences - including hate crimes and weapons offences.
Robert Bowers (46) is believed to have shouted anti-semitic slurs as he barged into the synagogue before opening fire.
Addressing a rally in the US, President Trump had a strong warning for those behind the attack.
"Through the centuries the Jews have endured terrible persecution - and you know that.
"We've all read it, we've studied it, they've gone through a lot.
"And those seeking their destruction - we will seek their destruction".
