Protesters take part in a demonstration close to the Syrian-Israeli border fence near Majdal Shams in the Golan Heights (Reuters)
Israeli troops opened fire on Sunday as protesters from Syria stormed a ceasefire line in the occupied Golan Heights, with Damascus saying six demonstrators were killed.
Hundreds of protesters rushed towards the ceasefire line, attempting to cut through a line of barbed wire and head into the Golan Heights in a repeat of demonstrations last month that saw thousands mass along Israel's north.
Similar protests were held in the West Bank, where hundreds demonstrated at Qalandia checkpoint near Ramallah, and in Gaza, where several hundred gathered in the north of the coastal enclave.
In Majdal Shams, on the occupied Golan, Israeli troops opened fire as demonstrators sought to push through the mined ceasefire line, which has been reinforced with two lines of curled barbed wire blocking access to a fence.
"Despite numerous warnings, both verbal and later warning shots in the air, dozens of Syrians continue to approach the border and IDF (Israel Defence Forces) forces were left with no choice but to open fire towards the feet of protesters in efforts to deter further actions," an army spokesman told AFP.
Updating an earlier toll, Syrian state media reported that six people were killed and over 100 wounded.
An AFP photographer saw at least 20 people with injuries, some soaked in blood as they were evacuated from the scene, while the Israeli military said it was aware of 12 casualties.
On the Israeli side, Majdal Shams locals pleaded with soldiers to stop firing as troops used loudspeakers to warn demonstrators in Arabic that "anyone who comes close to the fence will be responsible for their own blood."
Israel forces were placed on high alert after activists in the West Bank and Gaza Strip, and in Arab nations bordering the Jewish state, called for protesters to march on Israeli checkpoints and border areas.
Military spokeswoman Lieutenant-Colonel Avital Leibovitz accused Syria of orchestrating the latest Golan protest to deflect attention from deadly anti-regime demonstrations in the Arab country.
"We believe that the Syrian regime is focusing the world's attention on the border with Israel instead of what is happening there," she said.
But protests were also staged in Gaza and the West Bank, where hundreds of demonstrators marched to the Qalandia checkpoint by Ramallah, throwing stones at Israeli troops who fired tear gas and rubber bullets.
Ten demonstrators were taken to hospital with light wounds from rubber bullets, while another 20 were treated at the scene for tear gas inhalation.
Elsewhere, around 100 people demonstrated in central Hebron in the southern West Bank, while dozens of protesters tried to march from the northern West Bank village of Deir al-Hatab to the nearby Elon Moreh settlement.
In Gaza, Hamas police arrested around a dozen protesters who broke away from a rally at the entrance of the northern town of Beit Hanun, and tried to march to the Erez border crossing with Israel.
Sunday's protests, timed to coincide with the 44th anniversary of the Six-Day War when Israel captured the Golan from Syria as well as the West Bank and Gaza Strip, were planned as a repeat of massive demonstrations last month.
On May 15, thousands of protesters massed on Israel's borders with Syria, Lebanon and Gaza, trying to force their way across on the anniversary of Israel's creation.
Israeli troops opened fire on demonstrators as they stormed the borders from Syria and Lebanon, leaving six dead on the Lebanese side of the border and four dead on Syria's side.
In Lebanon, Palestinian refugees on Sunday staged a day of mourning but the Lebanese army banned any gatherings at the border with Israel to avoid a repeat of the violence.
But an Iranian delegation toured the border area and a parliamentary official from Iran waved a Palestinian flag in the direction of Israeli soldiers watching from the other side.
