MISHMERET, Israel — The Israeli military said it was reinforcing troops along the border with the Gaza Strip and calling up reserves after a rocket attack on an Israeli home wounded seven people.

Prime Minister Benjamin Netanyahu said he would cut short his trip to the United States after news of the rocket strike on Mishmeret, an agricultural town north of Tel Aviv.

In Mishmeret one house was completely destroyed, and at least one other house and cars were left badly damaged.

Israel's Magen David Adom ambulance service said it was treating 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.

The strike came minutes after the Israeli military activated air raid sirens in the area and said one rocket had been launched out of the Gaza Strip, a coastal territory 50 miles away where Hamas and other factions possess such weapons.

Smadar Castelnovo, a Mishmeret resident who lives opposite the destroyed house, said they were woken up shortly after 5 a.m.

"We heard the siren and we didn't think it was anything, but my daughter made us go into the reinforced room," said Castelnovo, still in her pajamas.

"My daughter was upset because we had left the dog out. We went out to get the dog and as soon as we went back in there was a very loud boom."

Police sealed off streets, and emergency services were working at the scene, as Israeli politicians visited to talk to media crews.

Netanyahu, who arrived in Washington on Sunday for a four-day visit ahead of an April 9 Israeli election, said he would fly home immediately after meeting President Donald Trump at the White House, as planned, later on Monday.

"In light of the security events I decided to cut short my visit to the U.S.," Netanyahu said, calling the rocket fire a "heinous attack."

The early morning attack came at a time of high tension ahead of the anniversary of Gaza border protests over the weekend, and Trump's expression of support for Israeli sovereignty over the occupied Golan Heights.

Gaza bracing

There was no immediate claim of responsibility from Gaza, where Palestinians were preparing for Israeli retaliation.

Israel told Palestinian officials it was closing all Gaza crossings as well as access to the sea from the blockaded territory.

Yahya Sinwar, the head of the Islamist militant group Hamas in the coastal enclave, canceled a planned public meeting scheduled for Monday afternoon, with Hamas officials citing "developments."

Netanyahu said his decision to return to Israel was made after he consulted with Israeli military and intelligence chiefs. He had been due to address AIPAC, the largest U.S. pro-Israel lobby, on Tuesday.

But early on Monday he said: "In a few hours, I will meet President Trump and immediately after that I will return to Israel to direct our actions close-hand."

His chief rival in next month's election, centrist ex-general Benny Gantz, issued a statement accusing the rightist premier of having "bankrupted national security" by permitting such attacks. Gantz, who is also in Washington to address AIPAC, had urged Netanyahu to return home.

Tel Aviv, Israel's commercial capital, and outlying communities had last come under a long-range rocket attack that caused casualties during the 2014 war with Hamas.

Two rockets were launched at Tel Aviv on March 14 but caused no injuries or damage. Israel blamed those rocket launches on Hamas, though a security official later said the salvo had been set off by accident.

The latest attack follows disturbances involving Palestinian prisoners in southern Israel. Palestinian officials said 20 prisoners in Israel's jail in the Negev were injured during violence inside the prison in the wake of "humiliating searches" by prison guards. Israeli officials said two guards were stabbed and wounded.
