Hussam Zomlot wrote on his official X account (formerly Twitter) that three young Palestinians: Hisham Awartani, Tahseen Ali, and Kenan Abdel Hamid, are studying at Yale University and other American universities.
He said they were shot last night on their way to a family dinner in Burlington, Vermont.
All these young men did "was wear the Palestinian keffiyeh", Zomlot said.
The Palestinian diplomat described the condition of the three young men as serious.
US media confirmed a shooting of three young men in Burlington.
She stated that the US police received a report of a shooting at half past six in the evening, Saturday.
Upon arrival, police officers found three Palestinian youths injured at the scene.
Authorities have yet to identify the shooter in the attack.
The Palestinian ambassador in London referred to the stabbing of a Palestinian child 26 times to death weeks ago in the United States, in an incident linked to the war on Gaza.
Zomlot called for an end to crimes against Palestinians and protection for them.
