Israeli Prime Minister Benjamin Netanyahu cut short a visit to the United States on Monday and the military said it dispatched reinforcements to the Gaza border after a rocket attack near Tel Aviv wounded seven people.

Axar.az reports citing foreign media that, Netanyahu threatened a forceful response to the long-range strike amid accusations from opponents in a closely contested Israeli election, two weeks away, that he had been showing weakness in the face of security challenges from Gaza militants.

Netanyahu, who arrived in Washington on Sunday for a four-day visit, said he would fly home immediately after meeting President Donald Trump at the White House, as planned, later on Monday.

“This was a heinous attack on the State of Israel and we will respond strongly,” Netanyahu said in a video statement.

“In light of the security events, I have decided to cut short my visit to the United States. In a few hours, I will meet President Trump and immediately after that I will return to Israel to direct our actions close-hand.”

The Israeli military said Hamas, the armed group that rules Gaza, fired the rocket that destroyed a house in Mishmeret, a village north of Tel Aviv.

There was no claim of responsibility for the early morning strike. The military said Hamas launched the rocket from about 120 km (75 miles) away, making it the longest-range attack from Gaza causing casualties since a 2014 war.

Israel’s Magen David Adom ambulance service said it treated seven people, including an infant, a 3-year-old boy, a 12-year-old girl and a 60-year-old woman who was suffering from blast injuries, burns and shrapnel wounds.

“It just made me feel really unsafe all of a sudden, which is a feeling I’m not used to,” said Nitzan Shifrin, a 19-year-old Mishmeret resident.

Israeli military chief spokesman Ronen Manelis said it was assigning two brigades to the Gaza area and that some reservists were being called up.

“We are prepared for a wide range of scenarios,” he said.
