Three Palestinians wounded in Gaza after Israeli rocket fire

Israel also arrested a number of senior Hamas members in the occupied West Bank overnight, including one of its leaders in the territory.

Late on Tuesday, the Israeli military said that an undefined "projectile" was fired from Gaza towards southern Israel.

A spokesman said that it was "very probably" a rocket but that it was not clear where it hit.

Palestinians in the coastal territory have fired both rockets and mortar rounds into Israel over the past week amid anger over US President Donald Trump's recognition of Jerusalem as its capital.

"In response to the projectile fired from the Gaza Strip at Israel earlier, the Israel air force targeted a Hamas military compound in the southern Gaza Strip," the army said on Wednesday.

Gaza security officials said that aircraft hit a Hamas naval base west of the city of Khan Younes and open land nearby.

Three Palestinians were lightly wounded in the strikes, the health ministry in the besieged Gaza said. No casualties were reported on the Israeli side.

Those arrested overnight included Hassan Yousef, one of the founders of Hamas. He was arrested in Ramallah, a statement from the Palestinian movement said.

Yousef is a member of the largely defunct Palestinian parliament elected in 2006 and was jailed between 2012 and 2014.

"He was arrested because of his involvement in encouraging and directing Hamas activity in the West Bank" a spokeswoman for Israel's Shin Beth domestic security agency said.

Yousef's son, Mosab Hassan Yousef, gained prominence in recent years after a film was released detailing his spying for Israel, called "The Green Prince."

Yousef disowned his son after he admitted to spying on Hamas for Israel.

Trump's December 6 announcement has sparked protests across the Palestinian territories, with four people killed and hundreds wounded in clashes or retaliatory Israeli air strikes so far
