Emir Hamad bin Khalifa Al Thani, has left Doha with a large delegation including his wife Sheikh Moza, Prime Minister and Foreign Minister Hamad bin Jassim and other ministers, according to Qatar News Agency (QNA).

The Emir is set to enter the Gaza Strip by land from Egypt given that Gaza has no airport or seaport, as Israel controls all the other crossing points.

The visit hailed as “very important” comes during a spike in tension between Israel and Hamas, whose armed wing on Monday threatened revenge for Israeli air strikes that killed one of its men and at least one other militant, AFP reported.

The Qatari investment project aims to rebuild the Gaza Strip, which endured damage during a huge 22-day Israeli military operation in December 2008 and January 2009.

The investment project seeks to build 1,000 homes for poor families in the devastated Khan Younis area in the south of the Strip.

“This visit has great political significance,” said Hamas government spokesman Taher al-Nunu, according to Al Jazeera.

“He is the first Arab leader to break the political siege.

Israel commented on the visit also. “We find it weird that the emir doesn’t support all of the Palestinians but sides with Hamas over the Palestinian Authority (in the West Bank) which he has never visited,” foreign ministry spokesman Yigal Palmor told AFP on Monday.

“The emir has chosen his camp and it is not good.”
