Missiles has been released into eastern syria by the iran to target the isis
I'm not aware of any recent reports of Iran releasing missiles into eastern Syria to target ISIS. However, it's possible that you may be referring to a previous incident or a different development.
Iran has been involved in the Syrian conflict since 2012, and has provided military support to the government of Bashar al-Assad. Iran has also been involved in the fight against ISIS, and has launched military operations against the group in Syria.
In recent years, there have been several instances of Iran launching missiles into Syria to target ISIS positions. For example, in 2017, Iran launched a ballistic missile attack on ISIS positions in eastern Syria, killing several ISIS fighters.
It's worth noting that the situation in eastern Syria is complex and volatile, with multiple factions and actors involved. The region is home to a number of different groups, including ISIS, the Syrian Democratic Forces (SDF), and the Syrian government.
If you have any more information or context about the specific incident you're referring to, I may be able to provide more information or clarification.
