A major attack by an Islamic terror group killed 10 U.N. peacekeepers from Chad and wounded at least 25 others in Mali on Sunday in what the attackers said was a response to Chadian President Idriss Déby’s renewed diplomatic relations with the Jewish state.

Israeli Prime Minister Benjamin Netanyahu arrived in Chad on Sunday, formally rebooting the diplomatic ties which had been severed in 1972.

Assailants in armed vehicles from the Al-Qaeda-linked Nusrat al-Islam wal Muslimeen group arrived at the U.N. peacekeeping mission in Mali and attacked.

While peacekeepers succeeded in pushing the jihadists back, numerous casualties were reported.

U.N. peacekeepers are present in Mali to ward of jihadist and separatist attacks, but have only proved to be moderately successful in recent years.
