BEIRUT, June 29 (Reuters) - A security deal between Israel and Lebanon risks entrenching a stalemate rather than resolving Israel's underlying conflict with Hezbollah by tying Israel's pullout from southern Lebanon to the Iran-aligned group's disarmament, a condition regional analysts and politicians say is unattainable.

At its core is a bargain few see as workable: Hezbollah has flatly rejected disarmament, and no Lebanese government has the power to enforce it.

Lebanon's President Joseph Aoun on Monday told the head of US forces in the Middle East that Beirut intended to assert its sovereignty over the entire country, with the army deployed right up to the Israeli border.

Aoun met Admiral Brad Cooper, the head of US Central Command, to discuss the Washington-brokered agreement signed last week by Israel and Lebanon aimed at a peace deal.

Cooper also met Lebanon's army chief Rodolphe Haykal, with the discussions addressing "the latest developments in Lebanon and the region", the army said in a statement.

WASHINGTON, June 29 (Reuters) - The United States said a high-level meeting on Iran would be held in Doha on Tuesday with President Donald Trump's top envoys Steve Witkoff and Jared Kushner attending while technical talks would also continue on the sidelines.

In a social media post on Monday, Trump said that Iran had requested a meeting and that it would take place in the Qatari capital without giving any details.

ANKARA, June 29 (Reuters) - Turkey expects next month's NATO summit in Ankara to emphasise alliance unity, President Tayyip Erdogan said on Monday, calling for the lifting of restrictions on defence trade and for Ankara's involvement in initiatives to bolster European security.

JERUSALEM, June 29 (Reuters) - The Israeli military killed three Palestinians, including a child, in an air strike on central Gaza on Monday, according to the health ministry in the devastated territory, despite a ceasefire that has officially been in effect since October.

An Israeli military official confirmed an air strike had been carried out, without providing further details. The Gazan health ministry said an Israeli strike occurred around 9:30 a.m. (0630 GMT) in Deir al Balah city in central Gaza, which is under the control of Hamas. Israel occupies around 60% of Gaza.

DUBAI, June 29 (Reuters) - Iranian and U.S. technical teams working on the implementation of an interim peace deal are expected to meet in Doha in the coming days, a source told Reuters on Monday, after tit-for-tat weekend strikes threatened to derail the fragile accord.

Mediators have established communications channels to de-escalate any incidents, and technical talks are set to continue, the source, with knowledge of the discussions, added. However, a senior Iranian official was reported as saying technical meetings were not confirmed.

BEIRUT, June 29 (Reuters) - Lebanon's Parliament Speaker Nabih Berri, a key ally of Hezbollah, on Monday slammed a U.S.-brokered agreement between Lebanon and Israel, warning it could lead to attempts to divide Lebanese and said it would not be implemented.

In comments to Lebanon's al-Akhbar newspaper, Berri described Iran-U.S. negotiations as the only realistic opportunity to secure Israeli withdrawal from Lebanon and that any attempt to separate Lebanon from the U.S.-Iran track would prolong Israeli occupation.

US President Donald Trump said Iran requested a meeting on Tuesday in Qatar, despite Tehran denying any direct negotiations were planned with Washington on the deal aimed at ending the Middle East war.

Washington and Tehran both have said they were sending teams to the Gulf state, but issued conflicting statements on most other details, including timing and purpose of the trip.
