Hamas Prime Minister Ismail Haniyeh arrived in Tehran Friday afternoon, where he was welcomed at Mehrabad International Airport by Iranian Foreign Minister Ali Salehi.

On the agenda for Haniyeh's visit was to meet with Iranian officials and "review regional developments," Iran's Fars news agency reported.

Late last month, Hamas spokesman Taher al-Nono said Haniyeh was going to Tehran at the invitation of Iranian President Mahmoud Ahmadinejad.

Earlier this week, however, highlighting the divide between Sunni Arab leaders and Shi'ite Iran, leaders from Gulf states warned Haniyeh not to visit Iran a planned, the Al-Quds daily reported.

According to the report, sources said "Officials in the Gulf states advised Haniyeh not to visit Iran due to tense relations," and "expressed concern over Iran's ambitions in the Persian Gulf."

The source said high-level officials in Qatar, Bahrain and Kuwait - which Haniyeh recently visited - urged him to cancel the planned Iran visit, saying "without a doubt, Haniyeh's visit to Tehran will have consequences."

Late last month, the Gaza-based Hamas leader departed the Strip for a tour of Iran and GUlf states.

A diplomatic source told Reuters that Iran had funded Hamas in the past with up to $300 million per year, but the flow of money had not been regular in 2011. "Payment has been in suspension since August," said the source, who spoke on condition of anonymity.

Analysts and diplomatic sources say Iran is unhappy with Hamas for its refusal to offer public support to its ally, Syrian President Bashar Assad, who has hosted the Hamas leadership in exile in his capital Damascus for the past decade.
