Likely just a common tit for tat attack in retaliation for the Israelis bombing the Iranian embassy in Syria

Here’s a past example

What israel did, attacking the consulate of iran inside Síria is really really fucked up. Iran played it cool and did this attack today, wich you could consider a very light response because attacking an embassy is casus belli (reason for war). But the usa will turn this into ww3 sooner or later, theres no doubt about it
