Arizona Tribune - Hamas names Sinwar new chief as region braces for Iran retaliation against Israel

The announcement came with the Middle East braced for Iran's retaliation over the killing of Haniyeh in Tehran.

Iran blames Haniyeh's death on Israel and has vowed to avenge him, while Hamas's Lebanese ally Hezbollah has also pledged to retaliate for his killing and that of its military commander Fuad Shukr in an Israeli strike in Beirut hours earlier.

Sinwar, who has been Hamas's leader in Gaza since 2017 with Haniyeh living in Qatar, has not been seen since the October 7 attack.

A senior Hamas official told AFP that the selection of Sinwar sent a message that the militant group "continues its path of resistance".

Israeli Foreign Minister Israel Katz said Sinwar's appointment was "yet another compelling reason to swiftly eliminate him and wipe this vile organisation off the face of the earth".

Analysts believe that he has been more reluctant than Haniyeh to agree a ceasefire deal.

Meanwhile, in a televised address to mark one week since Shukr's death, Hezbollah leader Hassan Nasrallah said his group and Tehran were "obliged to respond" to the deaths of Haniyeh and Shukr.

Nasrallah said Hezbollah would retaliate "alone or in the context of a unified response from all the axis" of Iran-backed groups in the region, "whatever the consequences."

Minutes before his speech, Israeli jets flew low over the Lebanese capital, breaking the sound barrier.

- 'Around the clock' -

With the region on edge, the United States said it was working "around the clock" to avert an all-out war.

It has sent extra warships and fighter jets to the region in support of Israel, and on Monday President Joe Biden held crisis talks with his national security team.

Biden also called King Abdullah II of Jordan, whose country helped down Iranian drones and missiles in an attack on Israel in April.

This was followed by a call with Qatari Emir Tamim bin Hamad Al Thani and another with Egyptian President Abdel Fattah El-Sisi, whose countries have been the key intermediaries seeking a ceasefire in the 10-month Israel-Hamas war in Gaza.

US Secretary of State Antony Blinken also called top officials in Qatar and Egypt.

"We are engaged in intense diplomacy, pretty much around the clock, with a very simple message -- all parties must refrain from escalation," Blinken said after joining other top officials in a White House meeting.

Iranian President Masoud Pezeshkian hit out on Monday at what he called the "criminal acts" of Israel "against the oppressed and defenceless people of Gaza", as well as for Haniyeh's killing.

"The Islamic Republic of Iran is in no way seeking to expand the scope of war and crisis in the region, but this regime will definitely receive the response for its crimes and arrogance," Pezeshkian said, according to the official news agency IRNA.

Israel has not commented on the Haniyeh killing but confirmed it killed Shukr.

It held the Hezbollah commander responsible for a rocket attack in the annexed Golan Heights that killed 12 children, calling him the "right-hand man" of Nasrallah.

- 'Playing with fire' -

Hezbollah has engaged in near-daily cross-border clashes with Israeli troops since the day after Hamas attacked Israel in early October.

Hezbollah said six of its fighters were killed in Israeli strikes on southern Lebanon.

The group said it launched "dozens of Katyusha rockets" at a military base in the Israeli-annexed Golan Heights in retaliation.

Regional councils in northern Israel urged residents to stay close to shelters on Tuesday after a barrage of rockets.

A European diplomat in Tel Aviv said "a coordinated response" from Iran and its proxies was expected against Israel but de-escalation efforts persisted.

"That doesn't mean there will be a simultaneous response from all fronts," he added, declining to be identified as he was not authorised to speak on the issue.

"We're telling them they have to stop playing with fire, because the risk of flare-ups is higher than at any time since October 7," he said.

Numerous airlines have suspended flights to Lebanon or limited them to daylight hours.

Lebanese national carrier Middle East Airlines put on extra flights for people wanting to leave or return, a company source said.

The Jeddah-based Organisation of Islamic Cooperation is to meet on Wednesday at the request of "Palestine and Iran", to discuss developments in the region, an OIC official said.

- 'Act urgently' -

The United Nations' rights chief Volker Turk called on "all parties, along with those states with influence, to act urgently to de-escalate what has become a very precarious situation".

The Israel-Hamas war in the Gaza Strip, triggered by the Palestinian group's October 7 attack on Israel, has already drawn in Iran-backed militants in Syria, Lebanon, Iraq and Yemen.

The Hamas attack resulted in the deaths of 1,198 people, mostly civilians, according to an AFP tally based on Israeli official figures.

Palestinian militants seized 251 hostages, 111 of whom are still held captive in Gaza, including 39 the Israeli military says are dead.

Israel's retaliatory military campaign in Gaza has killed at least 39,653 people, according to the Hamas-run territory's health ministry, which does not give details of civilian and militant deaths.

In the occupied West Bank, Palestinian officials said that Israeli forces killed 12 people in three separate raids on Tuesday.
