Twelve-Day War

The **Twelve-Day War** (also known as the **Iran–Israel war**) began following the Israeli strikes against Iran on 13 June 2025 with an operation named Operation Rising Lion. This is the first time both countries went to a direct conflict since 2024 but on a massive scale. Iran responded by sending ballistic missiles against Israel (codenamed Operation True Promise III), mostly in Tel Aviv and Jerusalem. As of 24 June, 610 were killed in Iran and 29 were killed in Israel.

This conflict happened when Israel is participating in the Gaza war, in which Iran supports the Palestinian movements and the organization Hamas. Iran has also been accusing Israel of killing Palestinian civilians (see Israeli war crimes in the Gaza war). Both sides once struck each other in April 2024 and another in October 2024 but escalated in 2025. Many Iranian generals and scientists worked for the nuclear program had been killed by Israeli strikes.

The United States, under U.S. President Donald Trump, has expressed concerns about the situation in the Middle East. The US is a major ally of Israel and has supported Israel for many decades, the US has participated in shooting down Iranian missiles and has officially joined the war with Israel against Iran on 22 June. On 23 June, Iran struck an air base in Qatar to respond the US' attacks the day before. In the same day Trump said that both Iran and Israel have agreed to a ceasefire, although both countries have violated it later and even Trump accused both but since then none have attacked each other.

The Houthis, an Iran-backed movement and military organization in Yemen, has shown support for Iran ever since the attack happened. On 22 June, after the US strikes on Iran, Houthi cancelled the ceasefire that it has reached with the US made by President Trump.

Most countries have criticized Israel's first attack and had told its citizens to leave both countries in case of safety. Israel warns that no citizens should leave the country and must stay inside the country. Israel has began evacuating people as the situation worsen. Many people claimed this war to be the first stage of the Third World War.

## Background 
Since the 1979 Iranian revolution, the relationships between Iran and Israel have changed from friends to enemies. Iran has called for a total destruction for Israel multiple times. Iran also wants to build nuclear warheads, which Israel fears that it could send a massive threat against Israel's security. During the Gaza war, Iran has accused that Israel is killing innocent people, particularly Palestinians, making tensions rise.

On 1 April 2024. Israel struck Iranian embassy in Damascus, killing 12 Iranians. Iran then responded by sending drones and missiles to Israel, Israel said it shot down 99 percent Iranian drones and ballistic missiles. On 19 April, Israel retaliated and began attacking Iranian sites and airports. Iran later told no retaliation was planned.

The situation happened again in October where Iran bombed Israel to respond the assassination of the Iran-backed terrorist organization Hamas leader Ismail Haniyeh. Israel then responded by a bombing operation on Iran on 26 October. This will not happen again until June 2025.
