TEHRAN, April 9 (Xinhua) -- Iranian President Masoud Pezeshkian and Parliament Speaker Mohammad Baqer Qalibaf have stressed that stopping attacks on Lebanon is an integral part of the ceasefire reached between the United States and Iran.

They made the remarks in posts on social media platform X on Thursday after Israeli warplanes launched a series of airstrikes across Lebanon the previous day, killing and injuring hundreds of people despite the truce.

Iran's president said the "renewed aggression" by Israel against Lebanon "blatantly violates the initial ceasefire," adding, "Such actions signal deception and non-compliance, rendering negotiations meaningless."

Qalibaf described Lebanon and the entire "Resistance Axis" as "Iran's allies," saying, according to point 1 of Iran's 10-point proposal to end the war, they form "an inseparable part of the ceasefire."

Qalibaf emphasized, "Ceasefire violations carry explicit costs and strong responses. Extinguish the fire immediately."

Israel carried out on Wednesday its largest attack in Lebanon during this war, claiming that its fight against Hezbollah is not part of the two-week ceasefire deal with Iran. The attacks killed more than 200 people and wounded hundreds of others.

The ceasefire was announced early Wednesday by the United States and Iran. The office of Israeli Prime Minister Benjamin Netanyahu said Israel would comply with the truce but would continue military operations in Lebanon.
