'TEHRAN (FNA)- Syrian sources confirmed that 5 British soldiers have been killed in ISIL missile strikes in Eastern Deir Ezzur.
The Arabic-language al-Watan newspaper quoted local sources in Eastern Syria as saying on Thursday that the ISIL missile attacks on the town of al-Sha'afah killed 5 British forces fighting under the command of the US-led coalition and wounded a number of others. They added that the wounded soldiers were transferred to al-Shadadi hospital in Southeastern Hasaka.
