Hamas chief Yahya Sinwar thanked the leader of Lebanon’s Hezbollah Sayyed Hassan Nasrallah for his group’s support in the conflict with Israel, Hezbollah said, in the first reported message since Sinwar became Hamas leader in August, Reuters reports.

The Iran-backed Hezbollah has been waging attacks on Israel for nearly a year in a conflict across the Lebanese-Israeli border that has been taking place in parallel to the Gaza conflict. Hezbollah says its attacks aim to support the Palestinians.

“Your blessed actions have expressed your solidarity on the fronts of the Axis of Resistance, supporting and engaging in the battle,” Sinwar told Nasrallah, according to Hezbollah’s Al-Manar broadcaster.
