Israeli airstrikes across Gaza killed at least 17 people early Friday including children, hospital workers said, as the new US ambassador to Israel made his first public appearance in Jerusalem.

Among the dead were 10 people in Jabaliya, including eight from the same house, according to the Indonesian Hospital, which received the bodies, according to AP.

In the southern city of Khan Younis, seven people were killed, one of them a pregnant woman, according to Nasser Hospital, where the bodies were brought.

The strikes came a day after more than two dozen people died in Gaza as Israel ramps up attacks, pressuring Hamas to return the hostages and disarm.

US Ambassador to Israel Mike Huckabee on Friday appeared at the Western Wall, the holiest Jewish prayer site in Jerusalem’s Old City. Huckabee inserted a prayer into the wall, which he said was handwritten by US President Donald Trump. "Those are his initials, D.T.,“ said Huckabee while showing the note to the media.

In his first act as ambassador, Huckabee said Trump told him to take his prayer and pray for the peace of Jerusalem, he said. Huckabee also said every effort was being made to bring the remaining hostages held by Hamas home.

A one-time presidential hopeful, Huckabee has acknowledged his past support for Israel’s right to annex the West Bank and incorporate its Palestinian population into Israel but said it would not be his “prerogative” to carry out that policy.

During his first term, Trump recognized Jerusalem as Israel’s capital over Palestinian objections and moved the embassy from Tel Aviv. Palestinian seek the eastern part of the city that Israel captured in the 1967 Mideast war as their future capital.

Huckabee's arrival comes at a pivotal time in the 18-month war, as international mediators including the US are trying to get a broken ceasefire back on track.

Israel is demanding that Hamas release more hostages at the start of any new ceasefire and ultimately agree to disarm and leave the territory. Israel has said it plans occupy large “security zones” inside Gaza.

Khalil al-Hayya, head of Hamas’ negotiating delegation, said Thursday the group had rejected Israel’s latest proposal along those lines.

He reiterated Hamas’ stance that it will return hostages only in exchange for the release of more Palestinian prisoners, a full Israeli withdrawal from Gaza and a lasting truce, as called for in the now-defunct ceasefire agreement reached in January.
