Israeli army arrested 11 Palestinians in the West Bank early Tuesday, including a senior Hamas member, Palestinian security sources and Israeli media said.

Most of the detainees were napped in Hebron city where Hamas official Aied Doudin lived. The Palestinian sources said that Doudin and some of his relatives were seized.

Israel Radio reported that the raid targeted wanted activists.

It also reported that two rockets were fired from the Gaza Strip and landed in Western Negev in Israel. The missiles caused no injuries or damage.

An Israeli army spokesperson told the radio that this was the fourth projectile fired from the Hamas-controlled Gaza Strip over the past 24 hours.

There has been an increase in rocket attacks recently from Gaza, despite Hamas' attempts to enforce calm. Observers believed that smaller radical groups are behind the attacks.
