According to Shin Bet, in June there were 98 firebombs thrown by Arabs in June, 50 of them in Jerusalem.
This was lower than the 129 Molotov cocktails hurled in May.
I don't know how many were aimed at residential buildings and how many at other objects like cars, but one can find plenty of photos and videos of Arabs throwing Molotov cocktails at houses.
Luckily, no one was burned to death in these cases that happen multiple times every day,
These stories often don't even make the Israeli news. But the people who throw these firebombs intend exactly as much harm as the presumed Jewish terrorists who threw the firebomb at the house in Duma.
